The other is a 2 bed and a 1 bed    The 1 bed studio is the only unit being rented at the moment

Check it out, it's on Amazon.

Sure Mark, although I actually hosted in NYC, not in SF:-I hosted for a little over 2 years, in a large studio which I had converted into a 3-bedroom.

I’ve also come across these prebuilt, tiny homes on Amazon.  

There is a studio that has about 65% booked for 2023 right now but it is $81 a night.

A maintenance and capex budgets vary by the size of the property, a multi that has 4 studio apartments vs 4 3/2 bedroom will have different budgets.

I took a hard money loan @6% / 4 years (payment is $700) of 30k to renovate the detached studio.

Not to mention our appreciation has been 8% higher than the US national average, because of the high demand for affordable housing.We also have huge corporations here like Intel, Amazon, and Google just to name a few.

I purchased a few books from the bigger pockets catalog on amazon.

I have a house under contract with a walk out basement that I want to make into a studio apartment for a house hack.
