Our tenants left without giving prior notice and did not pay for last months rent.

Every multi out there right now for sale are occupied with low paying tenants.

Despite the small town feel, lots of research companies, an Amazon warehouse close by along with high paying science, tech, research jobs and even Costco is now building here.

I get emails from people all the time from sites like zillow, apartments.com, etc saying "Do you allow commercial leases" (which is code for "can I STR arbitrage?"). 

more than likely you will need to speak to the land groups of home builders or the land and development groups of multifamily buying groups and most are going to be publicly traded. make sure you have enough housing units. if you provide more info I can help out. there's a million different niches in development and more than likely less than 10 buyers for what you are talking about in any niche. we just reached out to Greystar for apartment development site we are putting together that is a vertical development. we called their office for the midwest and messaged every single person on their team on linkedin. put the effort in and you'll get results. 

I am going to walk through the home and make sure he has done everything I have asked and that it looks good. is their any other step i need to take before i pay him his final cut or is it time to move on to finding a renter

Greetings BP folks,My wife and I are negotiating a deal in our area for a home that has a tax lien from the city and county.We have been working with the seller for quite some time and were offered the opportunity to purchase the home at a great price, we also have agreed to pay off the tax lien in addition to the purchase price. 

My sister is selling her house to me; however, we want to do a mortgage transfer since she currently has a 2.5% interest rate, but the bank will only pay what is owed on the current mortgage.

What happens few months later property got an offer and I want to accept but pay the rehab to curbio but it isn't enough commission for buyer and seller side. 

As to paying off mortgages,  most rarely pay as agreed over 30 years.
