Filters clean, ac cooling appropriately, etc. just to be sure it’s not a system issue.

Great that you joined the site!

This include cleaning, painting and doing any repairs to get the house ready to sell and I can hold selling rights for 90 days.

My only theory is he wants our mortgage to look clean until he has the chance to sell it to a big bank (it's a small private lender), and he's only looking out for the company's interests. 

Sounds like you want him out now and money motivates a lot of people.Make it contingent on the condo being in good condition and professionally cleaned so that the expectation is set before handing him over any money.

They have lots of good things on their site you may need.

I get that these places have an old school style, but can't you recreate that with modern clean looking materials. 

Hi all, I'm new to the site and in full on learning mode right now, so please forgive me if I ask any rudimentary questions.

@Michael Deering I have not heard anything of USPS vacating that site anytime soon.

People on this site don't like them because they don't have absolute freedom.
