Obviously the IRS could still redeem within the 120 days, but does having a new owner than the original purchaser at auction present any issues?  

I am 26 years old, and a small business owner in the greater PNW area.

@James SchindlerAre you mailing investors or are these primary house owners?

Ask to speak with some of their current owners and current/former tenants.

Owners cramming guests inside of houses that should only sleep 3-4 but hosting 8-10.

However, this strategy has been used successfully (without IRS challenge) by numerous property owners for nearly 20 years, including many public companies that have reported their transactions to the SEC, with the full acquiescence of their boards and outside auditors.

Ask to speak with some of their current owners and current/former tenants.

That includes many American home owners as well. 

double wide on land In our area will be worth 200k or more itself.. now maybe in a park.. but then you have restriction in most parks here that you cant turn your MH into a rental.. it has to be owner occ. 

I just noticed that the rental license registration form requests a property manager be designated if the primary owner doesn't live or work within a 20 mile radius.
