We call each other regularly and discuss things.

So you have an air handler that looks like a regular forced air furnace and it has an evaporator coil in it that gets cold or hot depending on what the thermostat is requesting.

I was thinking SB9 instead of ADU so it would produce a new sellable property.  

Auctions and foreclosure sales occasionally produce a decent deal. 

i am going to househack my 1st property so iwant to get a head start by analyzing properties that i am interested in. my goal is to airbnb (STR) the bottom half of the home to hopefully produce faster and higher income by making it look nice.and the i will be renting out one upstairs room while istay in the other one.I am currently using rentometer but its just giving me the monthly rent for the whole unit so iwonder if theres another site for just rates by the room?

I don't doubt that with a lot of searching you might be able to find some lower end condos or apartments which might produce a little cashflow with a low HOA but for SFH that game is pretty much over.Now can you find a serious value add fixer upper SFH, renovate it and rent it out for cashflow?

You are correct that someone would need to have an appraisal completed with local comps (SFH's), however, an investor looking for a turn-key vacation rental has to look at the revenue produced. 

If that happened on a regular basis I can see how that logic would be solid.

Most taxpayers choose option one if they also have other investments that produce income such as partnerships.

If the management firm has written a plan of regular inspections, it shows they will take good care of your property.4.
