My experience is that most parks where the majority of homes are park-owned are mom & pop operators who live close by and do the repairs themselves.

@Jordan Gilberti This is one of the toughest areas of this industry to accurately capture...especially flippers taxed as ordinary income...and at the end of the year, how many investors really do a deep dive on their properties and confirm actual ROI...not many...this is tedious (and sometimes disappointing work).While flipping houses is not a viable or sustainable industry, it works for generating vacation cash...the most successful flippers aren't flipping houses any more, they are lending or teaching other people how to flip houses...but why?

Google and other sites have keyword generators or suggestions, but I just can't find what I feel I'm missing.

@Angelo Pozzuto Most likely you also lost title insurance if you operated the title transfer through a quit claim deed.Nevermind the DOS clause, if the worst comes your way and the bank hits you with a letter, you just have to deed the property back in your name and DOS issue is corrected.
