She wasn't sure where I can purchase those forms.

Or put in specific provisions such as if one partner wants to sell, then it is an automatic sale (maybe allow current partners to have first option to purchase, etc.).

Anyone please have any advice or example/blank purchase contracts and assignment agreement forms I could modify?

You are doing all the right things right now in terms of gathering great information.

Alternative way could be purchasing this property with normal conventional rehab loan, which is a standard 30 year fixed loan + rehab funds being funded up to 95% LTV.

Any advice or information is much appreciated!

I am going to go a bit off topic here...I have been thinking about purchasing a rowing machine for a while now and this thread, and thinking about how much my physical activity has gone down in the last year (since I left the Air Force), is making me think about it even more.

@Danny Celestin- thanks   1) yes - there is a large  difference bwtween  investment property and  preimary residence pricing  2)  assuming the 2 quotes provided are for  investment  properties - these are not too bad for a 2-4 unit purchase 

Are you looking to purchase (and fix) the 2nd home?

Depending on the lender for a DSCR rental property loan, rates will be about 0.125% to .25% lower if you put 25% versus 20% down on an investment property purchase if it's the same borrower credit score and profile being analyzed.
