My concern with your park would be how to make the numbers work with only 8 homes  Rents would need to be fairly high and/or price very low for these types of deals to make financial sense. 

First of all, they are down fairly quickly.

I communicate very often with him.

But with the market in my area being fairly high, a reset could hurt! 

There seems to be a fair amount of savvy MHP investors who do very well with that here on BP.

It is usually very negotiable.If you cannot get owner financing. there is Private money financing which is fairly negotiated, but it is  usually a short term loan like 12 months. 

It would need new siding and skirting, and some updated interior, but I've been inside it and it looks fairly decent!

Fairly major airport in Phoenix. 

The first tenants were fairly nice tenants, mom and her two kids (both teenagers) who were very helpful, showed us around their place and got us upstairs (vacant) access; however, both complained consistently about the previous (still current?)

They refused to communicate much and did not pay their last month's rent, saying I should use the security deposit.
