Assuming he doesn't response/finish, file a small claims suit (assuming the amount he's been overpaid is small enough that small claims will cover it). 

The county got on board and raised the tax assessed values accordingly.Then came 2008...Values plumeted...law suits galore....jail time for fraudulent appraisers and lenders...even the NC Governor was on board (namesake) and now a convicted felon....I still see it today.

The question is whether or not you can be successful in either a) getting out of the suit once its filed, b) reducing your risk of lawsuit, or c) ensuring that you will prevail should it come right down to it.

Can you file suit...yes. 

Shop around for the best deal that suits your situation.

@jaime @Jaime Borbon I'd swim upstream a bit and develop relationships with brokers.

We are looking forward to diving in, (sink or swim) absorbing any and all information and advice.

I’ve been threatened with a lot of suits for people who were mad they didn’t qualify or mad they didn’t deserve their deposit back but I’m still waiting on those papers to be served.  

I'm a house hacker personally (on my 2nd hack 8 years in), I love the investing strategy, and I hope it suits your lifestyle!
