For a lot of things you can just look up material costs and assume the same for labor. 50% material and 50% labor holds roughly true for the entire project, at least for me here in Milwaukee, your labor cost will probably be higher in the Bay Area.100-125k spread would be tight, even for me here in Milwaukee.

Surviving the first few years is tough, but if you can figure out how to do that, you can have a 3-5% down payment (call it 15-25k) turn into 300-500k of appreciation over a 10-12 year period.

I’m thinking it might be tough to sell down the road also however.

Anything much higher and you'll find the #s start to get tough.

Self-managing either an Airbnb or long-term rental from out-of-state would be tough, as you never know when an emergency will come up. 

@Rod Merriweather Getting a LOC (line of credit) secured by real estate from a bank is going to be tough as the line of credit is viewed as a short-term liability while the property is a long-term asset.

As everybody has noticed the increase in materials and labor has skyrocketed which has thrown a wrench into condominium reserve studies. 

I could see how it could get up to $16K with materials for a service that large.

If you hold it more than 10 years you likely will do great, but in the short term it will be tough.  

An arborist would be who I would ask, this is a tough guess for anyone not there to confirm these can be moved with no issues.
