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.   

Labor/material are going to be different and need to factor that in4) new roof, new HVAC, new water heater, ac panel, replacing plumbing to PVCThese are very variable, if you are getting this from a licensed guy to do it and unlicensed.. is it a big shop or a local shop doing it, is the GC doing it they will put some money on the top so it will be more money5) framing (creating new bedrooms or baths)I would get all these quoted from a good couple of licensed guys and unlicensed to know your numbers to cents

I like the 'method' where the tenant puts a check on the inside of the electrical panel.

You spoke on a panel about home building, and I asked you a question from the crowd.

What about land use and zoning policies that exclude affordable housing or even the high cost of living.Did you know that since January 1, 2020, California requires new construction homes to have solar panels?

Its not near any major cities where someone might look at it as a long play for path of progress.Another option might be to see if a solar farm or wind farm company might be interested once its clear cut. 

We have had work crews from a local lab and solar farm (separate bookings, obviously) for 3-8 weeks that rent the whole house in the offseason.

Plus, they look so much nicer than a bunch of panels glued to the wall.For existing bathtubs, do a tile surround.

I recently moved an electrical panel for one unit of a duplex.  

The STR loophole would work on the properties above, and then I could connect you to my CPA who has some great strategies like investing in Solar to keep more of your money.
