My one takeaway as an investor and househacker would be to not succumb to the voice in your head that keeps focusing on "what can go wrong" - sure, a bit of anxiety is helpful to keep you on top of your game, but too much and you'll always be looking for the bad in every situation. 

One method is to set up a Google Voice account (free) and set it to only accept messages.

Not saying you can't use OPM, but you have to decide if it's worth it in that scenario to bring in other voices/opinions on your deal if you can own the whole pie by getting a mortgage. 

@Carrie ReymentWe use google voice to get a local number, then we actually answer the calls and put them into a crm to organize.

I would suggest getting a dedicated number (Google Voice, etc) just for your tenants.

I have a google voice number specifically for them.

@William Brown you can also get a free Google Voice number to put on your signs.

So all of the voicemails are recorded in the salesperson’s own voice and come from their own Google Voice numbers and the text messages are personalized as well.And this is just for one of the five markets he operates in.

And the one that says your partner must approve... etc etc.Attorneys can guide you but sometimes they are not up to speed on all the rules and laws. you really want to go have a chat with the department of RE in your state.. that's the definitive voice of if the way you are structuring your transaction currently is indeed selling without a license.. 

Paid cash; I partnered with M3 Innovations, Inc. on the deal, I put up the purchase money and they put up the renovation money.
