Converting a primary residence to a rental is the cheapest way most working investors will ever finance a rental house. You buy owner-occupied — VA at 100% financing with no down payment if you’re eligible, or a conventional program with as little as 3% down — live in it, then convert it to a rental and buy the next one as your new primary. Brian Nelson, a loan officer at Veterans United Home Loans in Columbia, Missouri, has run that loop three times.
The tradeoff is speed. This ladder produces roughly one property every three years, not one a quarter. What it produces instead is low-payment, long-amortization debt on properties you’ve personally lived in and inspected from the inside.
Below: how the sequence works, the payment math to run before you write an offer, the resale screen Nelson applies to every candidate, and the two local-ordinance problems that cost him a signed tenant and dictated where he bought his short-term rental.
Key takeaways
- Owner-occupied financing is the whole point of this model: VA at 100% with no down payment, or conventional at as little as 3% down, versus a conventional investment purchase with a 20-25% down payment and an investment-rate note.
- Nelson holds roughly three years in each house before converting it, and steps up square footage each time — 900 sq ft, then 1,200 under contract, 1,500 next.
- Check landlord registration and short-term rental ordinances before you go under contract. Nelson had a family of four signed before learning Columbia, Missouri required approval to operate as a landlord; the tenant walked.
- Carry six months of payments in reserve and assume something breaks. His rule of thumb: whatever you think you need for an investment property, double it.
- Self-managing saves 9% to 11% of rent, which is what lets him hold rent flat — same rent for five years, tenant just signed a fourth-year renewal — and skip turnover costs entirely.

How the Primary-to-Rental Ladder Actually Works
The sequence is simple: buy as a primary residence, live in it about three years, convert it to a rental, then buy the next one as your new primary. Nelson is on his third property under this model and has never bought a rental at an investment rate with an investment down payment.
The financing gap is the reason. As a VA lender, he sees eligible veterans buy at 100% financing with no down payment at all. Veterans United also writes conventional loans with as little as 3% down, though he notes the qualifying criteria for those are extensive. Compare either to a conventional investment purchase, where you’re bringing a fifth to a quarter of the price in cash and paying a rate priced for non-owner-occupied risk. Same house, materially different monthly payment and materially different cash outlay.
His ladder is also a square-footage ladder, and it wasn’t planned that way. His first purchase was a 3,000 sq ft, four-bed, four-bath house bought on the assumption of a family that didn’t materialize. He overcorrected into a 900 sq ft house. The property he just put under contract is 1,200 sq ft. The next one, he says, would be 1,500.
That progression matters more than it sounds. Each step up is a house you can genuinely live in for three years, which is what keeps the owner-occupancy honest, and each step down the ladder becomes a rental in a size band with real tenant demand. The 900 sq ft house is small enough that he’s converting it to a short-term rental rather than a long-term lease, on the theory that more cycles of guests beat one small monthly check.
Underwrite the Payment Before You Underwrite the Deal
Run the actual payment before you tour anything. Nelson blocks 45 minutes to an hour for what he calls a pre-approval consultation, and the bulk of it is spent on one number: what you write a check for on the first of every month.
The reason is that buyers arrive anchored to a wrong figure. Payment estimates on Zillow and Realtor.com, he says, are usually built on 20% down, a better interest rate than the buyer qualifies for, or taxes and insurance that aren’t calculated accurately. For a VA buyer putting nothing down, that gap can be large enough to change which price band they should be shopping.
The failure mode he’s trying to kill is sticker shock. The old pattern was a loan estimate landing a week after the buyer went under contract — after the tour, after negotiation, sometimes after the inspection. By then the buyer is emotionally committed and several hundred dollars into due diligence.
His position: some people get scared off when they see the real payment, and that’s the correct outcome.
Two practical points for investors running this ladder:
- A soft credit pull is enough to start. You can get a read on buying power without a hard inquiry, which matters if you’re managing score for a future financing move.
- It’s never too early. He’ll pre-approve people who are 12 to 24 months out. On a three-year-per-house cadence, that’s exactly when you should be mapping the next rung — while you can still fix a credit or reserve problem.
Come to terms with whatever money you think you have that goes toward an investment property — probably double it. You’re not going to buy a house where a tenant sits there with no complaints and nothing broken for the whole time you own it.

The Resale Test Every Conversion Candidate Has to Pass
Before you make an offer, think about the resale. That’s Nelson’s single screen, and he applies it to his own purchases and to the buyers he pre-approves.
The test isn’t whether the house checks boxes. It’s why one box doesn’t. A property can hit square footage, bathroom count, and price and still carry a defect that shrinks the future buyer pool. His examples of resale drag:
- A driveway at a 45-degree incline
- A two-story home in an older community where buyers don’t want stairs
- A bad neighborhood, whatever the finishes look like
None of those show up in a rent comp. All of them show up when you list.
Hold horizon sets your tolerance. Nelson has real hesitations about the resale on the 1,200 sq ft house he just put under contract, and he bought it anyway — because he doesn’t plan to sell for 15 to 20 years and because he has other properties as a backstop. His words: it’s probably not his best investment, but with other safety nets he can be more aggressive on this one.
The cautionary case is his father, a 40-year loan officer who owned rentals and, by Nelson’s account, got into some properties that were never going to be lucrative long term. Someone with four decades of underwriting experience still bought resale problems. That’s the argument for making it an explicit step rather than a gut feel.
If your hold is five years instead of twenty, the same defect is a pass, not a discount.
The Local Rules That Kill a Conversion: Landlord Approval and STR Bans
Check landlord registration and short-term rental ordinances before you go under contract. Both of Nelson’s conversions turned on local rules, and the first one cost him a tenant.
He had a family of four signed and ready to move into his first rental when he learned that Columbia, Missouri requires approval to operate as a landlord. He hadn’t known. His agent, two or three years into the business, hadn’t known either. The tenant found out, wasn’t happy, and the lease fell through while he was in the middle of buying his second property. He told them straight that he hadn’t realized he needed to be approved — which is the honest answer and also a lost month of rent.
The second rule he handled deliberately. Columbia restricts short-term rentals inside city limits. The 900 sq ft house he’s now converting to an Airbnb sits outside city limits, and he says that was intentional — he didn’t want to deal with the ordinances. That single siting decision is the difference between a legal STR and a use he can’t operate.
The lesson generalizes past Missouri. Registration, licensing, inspection requirements, and STR ordinances are municipal and they don’t announce themselves during a residential purchase. Nobody in a standard owner-occupied transaction is checking whether you can rent the house later, because on paper you’re moving in.
Put it in your pre-offer checklist: call the city, confirm what a rental at that address requires, and confirm whether short-term use is permitted. Do it before the contract, not after a lease is signed.
Operating Economics: Self-Management, Reserves, and Flat Rent
Nelson self-manages, and the reason is arithmetic: it saves him 9% to 11% versus hiring a property management company. He also lives ten minutes from the rental, which is what makes DIY management realistic rather than aspirational.
That saved margin funds an unusual trade. He has kept rent on his long-term rental flat for five years, and the tenants just signed on for a fourth year. Most landlords would call that leaving money on the table. His framing: he told the tenants up front that he’d keep their payment low and work with them directly, in exchange for flexibility when a repair takes a few days. He knows the family. He has zero turnover cost, zero vacancy, and no leasing fee.
Notably, his very first prospective tenant wanted no flexibility at all — they wanted him fully approved and everything done on demand. That’s the deal that fell apart.
On reserves, his rule for anyone new is six months of payments, and bank on something going wrong. You are not going to own a house where nothing breaks and no tenant calls.
Where he stops doing work himself: concrete and electrical. He’ll handle lower-level plumbing, flooring, drywall, and a bathroom update. When he does hire, the contractor buys their own materials.
His scaling limits are stated plainly. Around five or six doors, he believes a property manager becomes necessary, and he doesn’t want to own more than about ten properties total. He wants to stay small enough to remain personally available.
Where This Model Slows You Down
The honest cost of this ladder is growth rate. Buying one primary every three years caps you at roughly one acquisition per cycle unless you break pattern and buy straight investment. Nelson says the only way he sees growth in the next twelve months is if he does exactly that — and he expects to stay at three properties instead, being as conservative as he’ll ever be right after a purchase. Five properties in five years is his realistic number, not ten.
He nearly broke pattern already. An eight-unit came across his desk and he passed, because he hadn’t done the research. His read: a single-family with one family in it is cut and dry, and more units means more problems. If he does add outside the ladder, he expects it to be something smaller with solid rental history.
He also rates his own short-term execution as average. The 1,200 sq ft house he’s buying is a live-in flip — new carpet, bathroom update, drywall — and he admits he hasn’t scoped renovation costs as closely as he should have. Half-finished projects and an uninhabitable house are how that hurts you. His top constraint is a book of contractors he can rely on, which he named as the one thing he’d fix with a magic wand.
Capital comes next. He plans a HELOC to update the properties he owns, then 24 to 36 months of paying that debt down before buying a fourth.
Market conditions helped this round. With pricing softening and days on market stretching, he got the house about 10% under its list price.
Frequently asked questions
Is it cheaper to buy a rental as a primary residence first than to buy it as an investment property?
Generally yes, on both down payment and rate. Owner-occupied financing includes VA loans at 100% financing with no down payment for eligible veterans, and conventional programs with as little as 3% down, versus a conventional investment purchase where you’re typically bringing 20-25% and paying an investment-priced rate.
The catch is occupancy. Loan programs carry occupancy requirements, so the intent to live in the property has to be real. Nelson’s approach is to live in each house roughly three years before converting it, which is also long enough to know the property well. Confirm your specific program’s terms with your lender.
Do I need a landlord license or city approval before renting out a house I used to live in?
In some cities, yes. Columbia, Missouri requires approval to operate as a landlord, and Nelson found out only after he had a family of four signed for his first rental — the tenant learned about it and the lease fell through. Neither he nor his agent knew the requirement existed.
Requirements are municipal and vary widely: registration, licensing, inspections, and separate rules for short-term rentals. Call the city about the specific address before you go under contract, and ask about short-term rental restrictions too if that’s a possible exit.
How much cash reserve should I hold before converting a primary residence to a rental?
Nelson’s rule is six months of payments, plus the assumption that something will break. He goes further for anyone new: whatever amount you think you need for an investment property, double it.
The reasoning is that a rental never runs clean for the full hold. Expect repair calls, an appliance failure, and at least one item beyond your skill level that requires a specialist on someone else’s schedule.
At how many rental properties should I stop self-managing and hire a property manager?
Nelson’s read is five or six doors. Below that, self-managing is realistic if you live close — he’s ten minutes from his rental — and it saves 9% to 11% of rent versus a management company.
He also notes it depends on your market and what managers charge locally. His own portfolio ceiling is around ten properties, specifically because he wants to stay available enough to handle things personally.
How do I know whether a house I plan to convert to a rental will be hard to resell later?
Look for the one box the property doesn’t check and ask why. Nelson’s concrete examples of resale drag are a driveway at a 45-degree incline, a two-story home in an older community where buyers don’t want stairs, and a bad neighborhood — problems that don’t show up in rent comps but do show up at listing.
Then weigh it against your hold period. He accepted resale risk on his current purchase because he doesn’t plan to sell for 15 to 20 years and has other properties as a backstop. On a five-year hold, that same defect is a reason to pass.
The bottom line
Before you write your next owner-occupied offer, make two calls: your lender, for a real payment on your actual rate and down payment, and the city, to confirm what it takes to rent that specific address out later. Those two calls are what separate a working conversion ladder from a signed lease that falls apart.
