Criminal backgraound can be really tricky with today's Fair Housing laws but the past landlord verification and emplyment verification was apparently not properly done.

(You’re giving them $800/mo now and trying to reduce it to $650/mo)The PM will ensure proper notices are given and no housing violations occur.

Can I set up some sort of agreement or promissory note that formalizes this properly? 

Take ownership of your mistake and learn to do the proper due diligence recommended above😊

Im already educated on the proper ratio of wages to be taken out per my total income.

Further, I can't imagine the average tenant taking the time to properly maintain a swimming pool.  

I've been looking into the Direct Marketing method and my question is this: How can you properly analyze the propery/deal when you dont know the condition of the inside of the properties you're reaching out to?

The property has an old but in decent condition Single Wide Manufactured home (does need some updating) with land included (not a mobile home park).

Make sure there is proper egress from the bedroom window.

Search for VA Regional Loan Office in your search engine and it will direct you to the proper government website.I hope this answers some of your questions.
