Post-dated checks isn't bad as that would hurt her should she not have the funds or close her account...then of course I would just have to go through the hassle of eviction/collections.

*ALERT ALERT* – ALWAYS KEEP EXTRA FUNDS IN RESERVE FOR UNEXPECTED EXPENSES.

The problem is that you appear to be looking for 2nd position downpayment funding. 

Thanks for your input guys, it’s a big project for it being my first but I’m willing to take it on, the income potential is there and I can’t pass it up... the funds I can get, just want an idea of what I will be spending..

It's typically in a written agreement that should state after move in and all funds collected.

I have also flipped over 100 properties as a contractor  I should of obtained financing from the beginning instead of using all our own funds. 

Any advice people have on funding my next deal and/or property analysis strategies, is greatly appreciated.

if your scared of debt you should just by index funds .

You can't really cap occupants of a home, you can charge additional funds, for usage, wear/tear, insurance, etc.

Funds from your exchange account are combined with hard money to complete the purchase and improvement of the new property.
