How to Buy Rental Property With No Money Down: Sub2, Seller Financing, and Co-Living Explained

I’ll be honest — when I first heard “buy a house with no money down,” I rolled my eyes a little. It sounds like one of those late-night infomercial things. But the more I’ve been researching creative financing strategies, the more I realize there are actually legitimate ways to do this. They just require a different kind of work than saving up a down payment.

Here are three strategies worth understanding — especially in a market where traditional financing is getting harder for a lot of people.


Why Traditional Financing Is Broken Right Now

Before getting into the strategies, it’s worth understanding why this conversation is even happening.

The current market isn’t really an inventory problem. There are houses available. The issue is affordability — interest rates have made monthly payments on a standard mortgage genuinely difficult for a lot of buyers and investors. That affordability gap is exactly where creative financing strategies live.


Strategy #1: Sub2 (Subject To) — Take Over the Seller’s Mortgage

Sub2 is short for “subject to the existing financing.” Instead of getting your own loan, you take over the seller’s current mortgage payments. The loan stays in the seller’s name, but you get the deed and control of the property.

Why would a seller agree to this? More reasons than you’d think:

  • They’re behind on payments and need out fast
  • They’re relocating and can’t wait for a traditional sale
  • They’re burned out landlords who just want the headache gone
  • The property has issues that make it hard to sell conventionally

And here’s why it’s interesting for buyers right now: if a seller has a mortgage from 2020 or 2021, they might have a 3% or 4% interest rate locked in. You take over that loan, you’re carrying that rate — not today’s 7%+ rates. That’s a massive advantage.

Quick example: A seller bought in 2021 at 3.5% on a $250,000 loan. Their monthly payment is around $1,120. If you bought that same property today with a new loan at 7%, you’d be paying closer to $1,660 a month. Sub2 saves you $500+ a month from day one.

The catch: there’s a “due on sale” clause in most mortgages, meaning the lender technically can call the loan due when ownership transfers. In practice this rarely happens — lenders don’t love calling performing loans — but it’s a real risk you need to understand before doing a Sub2 deal.


Strategy #2: Seller Financing — The Seller Becomes Your Bank

We covered this a bit in a previous post, but it’s worth revisiting in the context of no-money-down deals.

Seller financing works when the seller owns the property outright — no existing mortgage. Instead of going through a bank, you negotiate terms directly with the seller. Interest rate, down payment, monthly payment, loan term — all of it is negotiable.

The video I was watching used a simple analogy: it’s like buying an iPhone on a payment plan directly from Apple. You get the phone now, you pay over time. Same concept, much bigger asset.

When does a seller say yes to this?

  • They’ve owned the property for decades and have a huge capital gains tax bill coming if they sell outright — spreading payments over time reduces that hit
  • They want steady monthly income instead of a lump sum
  • They want to pass income to their kids over time instead of a big inheritance that might get spent
  • The property doesn’t qualify for traditional financing anyway

The beauty of seller financing is flexibility. You can negotiate 0% down if you find the right motivated seller with the right problem to solve. The deal structure is only limited by what both parties agree to.

Where to find seller financing deals:

  • Expired listings — around 15,000 properties expire from MLS daily nationwide. These are sellers who couldn’t sell the traditional way. Worth reaching out directly.
  • Landwatch.com — surprisingly good for finding land and small multifamily with seller financing already built in, sometimes with $0 down
  • Investorlift.com — pre-negotiated Sub2 and seller finance deals already in escrow

Strategy #3: Co-Living — Turn One House Into Multiple Income Streams

This one I hadn’t thought much about before, but it’s actually clever.

The basic idea: instead of renting a single-family home to one tenant for one monthly payment, you convert the space into a co-living setup and rent individual rooms. Bedrooms, converted dining rooms, finished garage spaces — each one becomes a separate rental unit.

Platforms like PadSplit connect landlords with tenants looking for furnished room rentals. Individual rooms can rent for around $875 a month. If you have a 4-bedroom house plus a converted space, you’re looking at potentially $4,000+ a month in rent versus maybe $1,800 for the whole house to one tenant.

Combined with Sub2, this gets interesting fast:

Buy a house Sub2 with a low inherited interest rate. Convert it into a co-living setup. Now your rental income is significantly higher than a standard rental, and your mortgage payment is lower than what a new loan would cost. The spread between income and expenses is where your cash flow lives.

It’s more management-intensive than a standard rental — more tenants, more turnover, more communication. But the numbers can work out significantly better.


The Part That Actually Takes Work

All three of these strategies sound great on paper. But here’s what I’ve learned from researching this stuff:

The money part is actually the easier problem to solve. The harder part is:

  • Finding motivated sellers who are open to creative terms
  • Building enough credibility that sellers trust you with their biggest asset
  • Knowing how to structure deals so they actually work for both sides
  • Understanding the legal side — especially with Sub2, which has real risks if not done properly

None of this is impossible. But it’s not passive either. You’re essentially doing the work of finding and solving a seller’s problem, and the creative financing is your reward for solving it well.

Philadelphia has a lot of long-term owners — people who bought 20 or 30 years ago, have low or no mortgage, and are getting tired. Germantown, West Philly, Kensington — these neighborhoods have motivated sellers if you know how to find them and talk to them. That’s the real skill.
