If your Offer lets you "review and approve" of leases, and you feel they are not as expected and decide you can't live with the turnover right after purchase, than can discuss backing out with your agent.

The problem is if you work with conventional financing (most investors do starting out) lenders won't approve a 3-5% DP for the next property.

It took maybe a week or so for us to get our approval for our two cabins

The easier solution is to make the basement technically part of the 1st floor even if you won't use it that way, getting a third unit approved is not something that will be easy. 

@Orlando Glez-JorgePlenty of lenders will lend on this - if you go to Facebook and search for lenders with 100% financing with financing spelled incorrectly, they say they lend at 3% and loan amounts from $5,000 - $50,000,000These lenders will approve you all day long, then have you send them $5,000 upfront.

I don't believe section 8 in our area, here in se Iowa, will back pay for the time waiting for applications to be approved.

Write it down on paper and make it a goal that you'd like to find a house hack under a certain price point after being approved.

A loan-to-value (LTV) ratio around 70-80% with a straightforward approval process would be appealing.
