I use a wifi connected door lock and I send it personal door codes for each renter that activates and deactivates according to their arrival and departure dates.Maintenance contacts?  

For example the types of locks you have on exterior doors (California requires deadbolts on exterior doors to rentals.) 

A few things that I takeaway form the analysis:- I'm not sure if you've already locked in your mortgage rate. 

. $150 for the door (Home Depot) $30 1 gallon of green paint $40 hardware (knob / lock / etc)$300 to cut the door to size (non standard) , paint , install

Some are rate locked, have extensions built in and are lower than typical bridge.

When can I change the locks she has nothing in the unit pls help I'm in nj

Well, besides PITI, there's maintenance which is basically the amount you allot to take care of things like replacing a door lock that someone used a pliers on, broken glass, door weather seals, HVAC maintenance, supplies to maintain the lawn, termite treatment, replacement boards for the fence, caulk and paint, etc.

Refinancing allows you to lock in better long-term terms and pay off the hard money or recapitalize (pull out your own cash).

I have to extend my rate lock.

You can get one of these devices and plug it into her outlet.
