Make sure you account for this in your underwriting.  

My wife is an accountant and business consultant and not to say she knows more about the MHP industry than I do but she is the final decision maker. 

My parents have plenty of money and most of it is sitting in low risk investments such as money market accounts getting 4.5% interest.

Just adjust your numbers on your offer to account for the difference.

I see things being said at the Subto Community that actually concern me very much for the people involved.

BTW why are you involved, let the PM CO handle it . 

For appropriate financial advice, do extensive due investigation on prospective investments and speak with a real estate attorney, accountant, or financial expert.Good luck!

Also I would try to account for the summer months and see if they are certain to commit to a 12 month lease.

I spoke to them one time about a cash out refinance, and they told me the proceeds had to be kept in an escrow account for me to use for more investing, which I thought was ridiculous, so I went with CNB Bank instead.
