Far too many parks just 'give' a resident in the park free space rent to keep an eye on things and do light maintenance with no 1099 reporting. 

I completely agree with @Ashish Acharya's points about the cost-effectiveness of a HELOC and the potential credit implications if it’s secured by your primary residence.

All calculations suggest great investment for 4 bed 3 bath in good school zone, however once the tax estimator goes from $2200 to $9500 due to lose of tax credit from not being a primary residence it hard to see how to get property in SC.

Unfortunately, going from FHA on the departing residence to a ne FHA loan can almost never work for a few reasons. 

Owner financing and HELOC on personal residence How did you add value to the deal?

To me, I would just accept Zelle and update Avail if possible and look to see what the tenant is looking for in terms of repairs, how much rent you'll get from them, and if you want them as a resident.

no reports of incidents with our residents but there were some people injured and some homes damaged. 

You could do something like what you want if it was your personal primary residence and even then the interest rate would be ugly. 

Is that amount worth risking at this time potentially having to pay from your primary residence?
