Other than that I am looking to house hack a 2-4 unit with an FHA, and then refi out of it and roll into another, etc.

The recent surge in home prices has also pushed out many lower income families who can no longer purchase “starter homes.”Many of the affordable housing problems stem from the cost of construction, zoning restrictions, and local legislation.

Add steel wool and wood glue and push them into small gaps.  

Plus, the vaccine is getting rolled out which will curb the spread tremendously.

This pushed us to look for different alternatives, and learned about REI.

@Donald Hlava start by asking for a rent roll showing the rents for each unit, how many units are occupied and what the rental history has been.

If it's yes or maybe, keep it rolling.

As far as validating the rental revenue, there are a few things to consider: ideally the estoppels would be notarized; confirm the lease agreement information matches the rent roll, p&l, and bank statements (bank statement would show you how much they are actually collecting); request copies of the executed lease amendments or other written or side agreements the owner may have had with the tenant(s). 

Have you viewed the rent rolls and tenant leases?

For most tenants  they can't move somewhere else until the 1st so they do push it to the end.
