It might depend on whether the MH is in a park where you rent the lot or is on private property with a MH on it.

Obviously, the home could be sold as the old sq ft and the investor/buyer can just go and permit it for the increased sq ft,  but I would think that the county automatically will go and assess the home as soon as it changes hands since this the county has probably seen this before. 

@Abel CurielAt the moment the only thing i’m Doing is checking online sites and see what homes are being sold by owner.

I have an offer on the table for a private money loan of $310k to finance the purchase of two properties.

Get HML or private money and close. 

The place sold in a few days. 

I syndicate mid- to large size multifamily properties with private equity investors.

If you read my post https://www.biggerpockets.com/forums/223/topics/539116-second-flip-sold-and-bought-3-houses-in-a-single-day this is one of the places that I bought at the auction.

@Hadar OrkibiThe property is being sold as is 40k which is the land value.

It'd be great to partner up with some new friends or receive private lending :)Btw, I'm a huge fan of the site!
