I am an engineer and I've personally evaluated multiple properties in each subdivision we recommend.

Fair housing testing often uses the matched pair.

I see ai following a very similar path, in multiple ways. 

Have you stress-tested how many months of double vacancy you can handle before it eats into your down payment?

It’s not that it can’t be done — it’s that most lenders want:One unified lease covering the whole property, not multiple individual ones.Market-rate long-term rent comps that match what they can verify (hard to do with individual rooms).Here’s what a lot of investors do to make it work:Have a single “master lease.”

@Eric Van Laar having multiple sources of data and different ways to validate the same data always helps. 

That said, I wouldn’t rule out using some financing if it means you can scale faster and get into multiple solid assets.

@Zachary Sneed - Submission of multiple mortgage applications at the time of each purchase should not be an issue for your credit score, as long as you do them all within a short period of time (such as within 30 days). 

If the deal isn't in contract, all numbers and terms are hypothetical and may not be worth the lender's time and effort.Before signing a contract, I recommend getting multiple contract estimates and inspections (if possible) to have a firm understanding of how much you'll spend on repairs to complete the deal.

I’ll stay in my lane here and focus only on the tenant screening part of your question.Use a full background report, not a shortcut.Look for credit, nationwide criminal, eviction history, and judgments or liens that pull from multiple databases, not a single source, and are reviewed by FCRA-certified screeners.
