There were some minor repairs I had to address, but she made me install fire doors with auto-closers, because I was renting it as a triplex...

The units are 500sqft each and currently have no ac or heat installed. 

I need to install a W and D in a 1 bed rental just south of Boston, in Weymouth.  

I installed the above Camera because it's completely battery operated, Z-Wave and has a Solar attachment.

This should put you in a better spot since it will be an installment account.For Airbnb to be used, I hope you have some proof of income for that specifically showing on tax returns otherwise the chances of you being able to use that is slim to none.

Since your young and eager, you might also spend a year working for a general contractor....learn how to do all the repairs and installations you can.

I have installed floodlights and camera's.

I’ve also considered installing a built-in vacuum pan in areas that appeal more to families.

My GC friend installed new kitchen cabinets, refinished HW flooring, painted walls, new bath.

Most installers will move the items from room to room.
