During the contract period, suppose the seller decides they want out of the deal, what does a wholesale do?

If closing is extended for any reason past April 15, EMD is immediately released to seller and is non-refundable and close of escrow will be extended  to May 30th.  

At 35% down, that extends to ~$1.7 Mil in properties. 

ROI is a rate of return, not a payback period. 

Hence the 6 months seasoning period.

If you are a good tenant, you can always extend your lease on a month-to-month basis.

What I discovered is something I have never seen anyone speak about on Bigger Pockets (I am sure someone has discussed this I just have not seen this idea discussed at all...or anywhere in my short research period on cash flow and real estate properties.We hear everyone speak about Cash Flow, NOI, Cap Rate or Cash on Cash returns.. however I think there is another important benchmark for investors to consider when deciding their down payment percentage and financing levels because of their effects on cash flow...Capital Cost per $1 of Cash FlowOne of the most illuminating aspects of real estate investing is financing isn’t bad...Having spent all of my life not accumulating debt this has been a difficult psychological barrier to break through.

If you are going to owner-occupy, you also want to benefit from the OO preference periods offered by HUD, Homepath, and Homesteps.

So it seems the first few properties might be slower since I would use conventional bank mortgage loans and then wait a seasoning period (6-12 months ?)

Unfortunately we were planning on doing all of this in July but his current contract is up in mid-April 2017 and we haven't made any decisions whether he will re-enlist, extend, or separate.
