If you are going to take on a 203k, I implore you to do your research and find a reputable contractor who has experience working on these previously.

Any recommendations on reputable real estate agents?

Within the Chattanooga, TN MSA, we're usually around $3500 for move and set up on piers from a reputable company.

A couple of possibilities you could look into is narrowing your search criteria significantly so you become "the guy" who buys this type of property in such and such an area, OR be content among other investors having the same access, develop a reputation as an investor who puts their money where their mouth is and pulls the trigger on deals.

Always good to know who's reputable.

If you can sell within 30 days get rid of it, if you can re-lease it for at least $100 more (to a reputable tenant) keep it; I would hold on to as much cash as possible - there are too many unknowns in 2021.

Assuming they are a reputable firm, they might have 100s of properties or doors and most do not ever actual drive by unless there is a specific reason. 

That being said get a couple of estimates from the national and local termite companies the key is to make sure that whoever you use has been in business for at least 10 years and has a good warranty but they stand behind and solid reputation.

Some of them get annoyed, but if they lost a clients money, that could wipe them out from a financial and reputational standpoint. 

I'm confident this is the kind of action that will develop the reputation that you don't want to have in your sphere.
