I'm wondering if a) I can increase rent at all (or did I need to give notice 2 months in advance) and b) if the tenant signs another lease, can that be for higher rent (annual, month to month, etc.)Essentially, I want a higher monthly rent payment for the increased exposure of not having a tenant for the entire year. 

@Ryan B. section 8 does not work that way in DC. 

Back of the envelope, there's plenty of margin for cashflow.Most of my experience has been investing in B and C-class multis in Providence, RI where units are closer to $80,000 a unit in decent condition, renting for $900 a month.

@Nikhil NirmelYou should start a fund and follow reg d 506(b) if you want non accredited investors.

The trouble I am facing is, I am international student currently in school on a F1 visa.

When I go to take out a loan and I qualify for say the lowest rate, will banks tack on 25 basis points b/c I took a COVID-modification?

We bought the second (B) in 2008 for 413k and it went into service in 2014, we bought the third (C) in 2013 with a tenant in it for 126k.

If rehabbing, with the right numbers you don’t need anything down. 25-30k down will get you a few solid rentals in good shape in B/C areas too.

The property is a single family home located in class B neighborhood in Madison AL.
