After everything was fixed and they listed the unit, apparently they claimed that I was not allowed to have any understanding of who would be renting my home due to potential bias and discrimination (this is the first time I have not been able to view applicants general profile (credit score/occupation(removing any identity markers)), but fine, I let them choose the tenant and so far there hasn't been any issues.

They are basically telling you to trust them with no ability for you to verify.

@Frank SichelleThey all have the past performance is not indicative of future success and for anyone who shows a history of prior returns without having it third party verified is like saying I went fishing alone and caught 20 fish including the largest bass ever.

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

I just purchased 24 units (three identical 8-unit buildings) that share a parking lot.

Just verify they did not add any further stipulations.

Can the LLC lend money for 50% of the purchase price and be considered "verified funds"?

Hello Misael, I would do a thorough market research to verify that you can get the rent increase you want, you might find out that the market is oversaturated with rentals.If you are trying to raise the rent $100/mo, 1 month of vacancy ruins your rent increase for the whole year.I would list the property for lease 45 days before your tenant's lease expires, if you have your property priced right you should get some applicants before your lady moves out.
