Traditional HARP loans were for GSE loans originated prior to May, 2009 and Fannie/Freddie loans were subject to conforming limits so, it wasn't a HARP loan if there was a refi in 2017 and for that amount although, if the loan balance was ten times lower?

You’re betting on appreciation and choosing to lose money monthly (rather than increasing a down payment) to make that educated guess and keep capital in the bank.

Tenant’s use of such furnishings shall be “AS-IS”, and Landlord has not made, does not make and hereby disclaims any representations or warranties (including, without limitation, any warranty of merchantability or fitness for a particular purpose) as to the physical condition of the furnishings or the suitability or usefulness of the furnishings for Tenant’s intended use.

Is there a statue of limitations on this type of event?

Just my two cents... especially since you can just re-use your VA loan when you move (granted you haven't spent your limit on it).

There is also a height setbacks and sometimes a FAR (floor area ratio) which limits how much you can built.

But, once you get the hang of things, the sky's the limit from there.

Some of the limitations with just calculating the cash flow is that you're not taking into account all of the sources of dollars coming in. 

For any client I work with that has limited knowledge on the subject, I extensively explain the home-buying process (including financing) whether they want me to or not.

@Tony C. remember the advice: "Don't bet long term with short term money."
