This investor is on the higher end as he is looking at Bel-Air only.

Since then we purchased 2 more houses and an antique shop (true entrepreneurial spirits :) with my brother and another rental with a back house on our own (back has long term tenant and front was air bnb'd over the holidays).This year, my goal is to sell our primary house and move into our house with a back house so I can house hack once again and start growing exponentially on our rentals.

Now, I can't tell if your rentals are short term (like Air BNB) or long term (like 12 month leases) so maybe some details on that will help us give a better recommendation but usually investors are working with smaller banks. 

@Caitlin BigelowThe $170k covers the cost of the entire 800 sqft addition (all new addition) project, including basic furnishing including air-conditioning and oven. $500/sqft is a rip-off.

Bid it out from a few people, quotes are usually free. expect some plaster work because they will likely have to bring it up to code, And almost can guarantee knob and tube if it’s historic. 

May even meter back the heating bill to the tenants but that still in air. 

What’s that process look like for those of you that use Air BNB for rentals?

@Brad Wood I would recommend Michael Bonsby Heating & Air.
