Its called a mail away closing done all the time.open with title company have them hire a mobile notary if you can't get the seller to go to her bank for notary.  

I felt that there was no more upward mobility for me at work, and with both my wife and putting in 11 hours a day so we could afford to live in one of the few useable school districts for our son (that we weren't seeing for more than a couple hours a day), we felt it was time to realize the appreciation on our house and jump ship.

Funny enough, I joined BiggerPockets from a member of a mobile game that I play in my down time at work.

Currently I am examining mobile home investing for the cashflow benefits in order to build up more capital.

What type of apps have you built before?

I clocked 12 minutes the last time I attended an in person closing in houston (I normally have them email docs, send to mobile notary, and sign where ever I'm at)Anyway. 12 minutes from my parking my car to getting back in.

There is a mobile app to allow me to check on my books. 

Finally, get the big box stores like Lowes, The Home Depot apps,  whatever is in your area and look up costs of supplies.  

I've seen more and more people use Venmo, a phone app.

Earlier today I made this post using the mobile app which is a bit more clunky to navigate.
