We added a door that we deadbolt to separate our side from the airbnb side, and I had to have some electric outlets and an overhead light to the airbnb side, but other than that everything was updated already and we just had to furnish the property which was really nice and made the process pretty easy. 

@David De La Torre it is common for electric and gas to be turned off when a tenant moves in, forcing them to turn it on in their name. 

New roof, new water heater, new Electrical panel, New HVAC, new Concrete driveway, new Concrete steps & walkout basement, Open space of kitchen and living room, fully finished basement with wet bar and new full bathroom, new windows.

Likewise, major alterations and change of use would require the structure to meet the new HERS (Home Energy Rating System) score.

I ended up living here longer because I got into real estate full time and didn't have the energy to finish fixing up, but moved out a couple months ago and it's almost ready to rent out as 2 units for Airbnb's or mid-term.

It's going to drive you crazy and you've got bigger fish to fry... you're building your business and all the stress and energy you are pouring into this is taking away from that. 

The time, energy, and lifestyle capital can drain your resources when you need to visit, build your team, manage your team, and how and when to exit. 

It's kind of like a a guy who gets really excited about something touch really really fast and you can't understand a word he says sometimes you have to slow it down  I've also found that I'm not saying he is but I've also found that in my life I'm 61 years old a lot of hucksters do the same thing  because they know if you show energy and excitement in a presentation more people will sign up then if you're dry as a bone

I love the idea of renovating your carriage house - does it have any water and electric hookups already?

As far as positive ROI - I'd like feedback on the following items:-Switching to tankless hot water heater (current water heater doesn't look so hot)-Upgrading electric panel to a Span Smart Panel.
