How many lots in those neighborhoods sold near that date to establish comps? 

As @Jonathan Greene mentioned this is kind of a dated strategy in the new price/interest rate environment.

I currently have a 11 property portfolio under contract for a few months now with no closing date in sight.

Property radar subscription may give it to you.. or a GOOD VA could compile in the counties your interested in. then up date it weekly as new private DTS are recorded

Find Brandon Turner anywhere on the internet for information on it.  

I suggest like one of those Canadian get-aways where it's awesome fishing, water sports, and no internet or cell reception. 

Even large and small businesses with intangible residual services like TV, internet, security, pest control or the local contractor with remodels in process could fall behind on payments revenue contract. 

I told her I wanted a haircut , not a date.

Can I do it as an investment property first and move into it at a later date?     

Everything is up-to-date in realtime so I could do my taxes any day of the week!
