Hi BiggerPockets community,We are a married couple based in the California Bay Area, both working as software engineers with a combined income of close to a Million USD.

And if they are a hobbyist/part-time builder, then they should engage the proper professionals, i.e. a title officer, civil engineer, architect, contractor et al to assist in reviewing the project's feasibility.

This will allow the team to develop and review project processes and management strategies to move forward with more challenging, yet rewarding, properties.I come from a very process-oriented background (Mechanical Engineering), and my goal is to learn and develop each step of the process, from start to finish, to continuously improve the team and ROI of each project. 

The GC can handle the entire project, coordinate different subcontractors and make sure the project is completed per building codes - especially if the rehab is complex or involves multiple trades like plumbing, electrical, and carpentry.

To avoid the risk management/insurance that comes with tenants' wood fire use:I'm thinking to seal the chimney cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.

A small bathroom can be gutted and drywalled new tile new electrical new shower everything in five days or 40 hours. with two guys. 

@Dean Malka 10k for average kitchen and 5k for average bathroom Flooring is $4 a square foot for LVP HVAC $5k Electrical panel $2k.This is all ball park.

It's in the very beginning stages (still talking to the arquitect/engineer firm.

In the Parlor floor we added a large-ish kitchen with electric oven and cooktop that goes to the sub-panel that belongs to the Parlor floor, making it a nice 800ft 1 bedroom apt, with access to a shared backyard.   

We focus on CapEX before beauty. as a realtor we understand selling or renting homes you have to make the home function, Roofing, windows, electrical and plumbing. after we address these we focused on beautify making sure the upgrades match the area and is forward thinking with color scheme, flooring, and flow.
