Personally I'd use it as a DP for a hard money loan on a flip or BRRR.

However, it's hard to know whether that person is marketing and operating their STR well or not.

Some have online systems, and others require you to go in person.

I'm not a fan, of this idea, but there are some property managers around that charge $150/person app fee. 

But one point that wasn't made ... if a storm comes through, and even if YOU don't make a claim but most everyone else does, YOUR rates will still go up too. (95% of the time) Because they gauge the rates not only by personal details but also by the claims in that coverage area/zip code. 

I personally know two people who are flipping mobile homes and have good success. 

If in doubt, consult with your tax professional for personalized guidance.

I have personally spoken to 3 attorneys who all said the same thing as you, and I have communicated the same to the board.

They require you to have at least 3 tradelines, which can be credit cards, auto loans, a mortgage, personal loan if recorded.

I will get into details as to who is on my loan phone call list and who I ended up doing business with as soon as I close and I hope it will help the next person going through what I did.
