Isn’t the advantage of MHP ownership the fact that you own the land (pad sites), have limited maintenance and limited management, and that tenants tend to be long term because mobile homes are costly to move? 

I serve on the board of the local REIA (CFRI..net) and connected to the investor community here as well as being a full time Realtor®.

I've also visited a site and deterred from offering because I won't do tear downs. 

You can't go off of the cost estimate on permits and even beyond that, design, site work and a number of other factors will play a significant role in costs.

Use the "search the site" feature of BP and you will find a wealth of good info on the topic of "smoke odor".We remove carpet and pad. 

They charge exorbitant fees above the rate you get as the owner and they list on third party sites at rates way above what they pay you.

Utilities, site upgrades, engineering?

@John Mason Hi John, I live and work with realtors that serve that area.

There are a lot of great licensed and experienced pros on this site that are happy to answer basic questions, but don't turn to an estate planning attorney on here and ask them to prepare your will for free in the DMs.

It sucks to live in a job site, but you can go slow and conserve cash as opposed to renovating the entire place on a deadline to get it rent ready.
