We've cut our teeth on the NPN's since 2008 and the returns have been great for us, but it's also added some workload as well, but its also nice with a chunk coming in regularly that are now performing monthly.As far as the comment on guru's telling new wanna be note investors to mail out mailers to track down new owner financed notes, I couldn't agree with you more!  

You can skip the Deals on Wheels book, it's along predatory dealing and financing, once allowed but now such is really something to avoid as the federal laws have teeth now.As Michael mentioned, you're dealing in chattel liens with personal property unless the home has been converted to RE, not in your case if your homes are in parks.

@Russell Brazil @Wayne Brooks  I cut my teeth selling land in my early years.. as an 18 YO agent I was too impatient to work with buyers that needed to use a bank LOL appraisals inspections etc etc.AS such I only sold land and I doubled ended everything I sold.. if its rural land and it sounds like it,  the buyer not finding it is very common.. a lot of my listings were up in the national forest north of SF ..

How do I broach this subject in a sensitive manner. 

We've been able to close them in less than a half hour (with a lot of wailing and gnashing of teeth). 

The courts have been traditionally sensitive to this issue.  

I am fortunate enough to have married a partner who is open to real estate and our plan in the next year is to cut our teeth on our first real estate deal. 

I know using a C-Corp for real estate investing is frowned upon by many since you can not take the personal deductions, but if your funds are in a retirement account, this was the only way I could find to utilize them with IRS approval.I am told IRS is sensitive to distributions being held in LLC's since profits flow through to members on their tax returns - IRS might consider this an early withdrawal and consider fines.Suggest professional advice so you do not have a hassle in the future and maybe lose your investment funds.

This is different from OP's question of filling in complete app form, which contains too much sensitive personal information just to see the place.

Just imagine how many more times these sensitive creatures would have been offended over the course of the lease term.
