However, since you already own a duplex and SF one idea is to invest in what you already own.

A thermal camera inspection would give better idea if its because of cold air getting in or the room does not have enough hvac / heat source

But of course the gurus will still take your money and not give you any idea that what they are teachingis legal or not..

You want a hustler, not a top performer, if you want check-ins.I appreciate the candor and would definitely agree that my framework is all in theory until I can get a proof of concept for these out of state deals.I like your idea of pushing my boundaries in CA.

Quote from @Aditya Kohli: @Hamidou Keita I would recommend if duplexes are limited if you can get a 4-5 bedroom house and either rent by room for house hack or splitting a big house into 2 and adding a kitchenette and separate entrance as a more cost effective ROI option  Great idea.

I’m back now and looking for some guidance on an idea that caught my attention.An old high school friend of mine has been buying older houses, either renovating or tearing them down and rebuilding, depending on their condition.

Any idea about this?

Just throwing ideas out there.

Does anyone know, or have a good idea, about the difference in returns on entitling & developing the land for each scenario, with final objective to sell to a builder to build and sell the structures him/herself.  

I really like the idea of building in that 10-15% buffer for the unexpected.
