Does this kind of researcher exist for accredited investors?

But if you do not build out further than your existing porch, that should not be a problem, but you should give them a revised drawing. even a second floor addition that follows the existing structure may need to go before zoning because the set backs may have changed since the house was built and would trigger a variance. it doesn't hurt to ask them and ask what they would require, it would show them that you aren't trying to put anything past them.

All over California, it is almost non-existent.

Welcome Andrew,  You came to the right place at BP, I wish it existed 10 years ago when I started. 

They do exist and I found that person by looking for a new career path.

Look for opportunities that you can purchase subject to the existing mortgage with a small downpayment.  

There are some recommendations that I wasn't aware existed to creatively finance or reduce the cost of this 4-plex.  

I emailed the three REIA's in my area and none of them exist anymore.

When you split a building into condos, they are treated as separate units which will likely have the same type of construction but unit mix and square footage should be vastly different, making them not comparable.If no multifamily sales exist, then the next best thing will be a single family of similar construction and square footage.  

If you don't, it's possible to get one with a brace and install it through the existing hole in the drywall; you don't *have* to go into the attic or tear up the ceiling.Whenever I am in the local Habitat ReStore, I notice that they have a few fans, but they always have several sets of glass shades for the lights.
