First Major Renovation Project - Does this Quote Sound Right?

[Barrett Lund]

Still learning my way around BP, if this is not the right area to post I can move it. 

I've decided to completely update and renovate my fourplex + detached unit (5 total units) and I am working with a referred contractor and have a quote for the full project. I have nothing to go off of to know if this is a reasonable price.

My fourplex was built in the 1940s, the detached unit was built in the 1980s. The fourplex is roughly 2400 sq ft, each unit is 600 sq ft with 1br/1bth all identical. 
The detached unit is about 800 sq ft and sits above a carport. This carport can't fit any regular sized cars in it because of where the beams that support the structure above sit. 


This is everything I am having done:
New kitchen (cabinets and tile flooring) and new bathrooms in all 5 units
3 of the units will have their hardwood floors refinished, 2 will have new hardwood floors.
- New doors, new windows everywhere
- all new plumbing everywhere
- Foundation repair for main fourplex 
-Brick repair for fourplex
-Brick and complete exterior painting of all structures
-Awning repair
-Communal entryway to fourplex remodel 
-Replace beams for detached unit and replace with one larger beam that allows for 2 full size vehicles to be parked there, then refinish the space with paved concrete and add commercial rollup garage doors to be able to fully secure the spaces.
-Remodel my 200 sq ft shed that is used as the washer/dryer area. 

I was quoted 155k - 170k for everything above.
