Here's a quick link, to which I am not affiliated or even familiar with, but which seems to address the issues you are looking at: http://www.email2db.com/ You might also look into an SMS (text messaging) solution so that it appears that you are communicating quickly and efficiently with your guests to build those oh so important reviews.http://www.orbisasia.com/solutions/automated-sms/Of course listening to J talk about his AirBnB success has set this new deal I'm working screaming through my head and how to take it and convert it into a 13 unit AirBnB complex.  

Guess that is why everyone is screaming about the need for rent control.San Mateo 3/2 selling for $1.6M (roughly $8400/mo PITI) would rent for roughly $4200/mo.But that is still roughly $4K/mo you could put into investments elsewhere.This should solve your DTI issue, but may, or may not, be a better investment in the end than just sticking with your primary.

I am no economist, but the whole thing SCREAMS "bubble."

It screams Motel 6

that screams someone will be disenfranchised. 

And (I think this is the hardest) as the kind of screaming deals investors want.

If anything, "durable" surfaces tend to scream "rental!"

We screamed that we hated them.

there just isnt a whole lot of things in that area that scream the need of a STR. not saying you cant get renters, there just isnt a lot to attract them. 

If someone will pay a wholesaler $50k, then that is obviously a screaming deal.
