Most interested in single or small multifamily rentals and FI, but there's good stuff in every show.

That's the "if you've lived in it for two of the last five years you can exclude $250K (single) or $500K (married filing joint) from capital gains tax" rule. 

It runs about $450 if your just getting a single unit.

My husband and I (together) jointly own our personal home in CA (we have a mortgage on it).My husband alone owns 1 vacation property in ME, 3 single family rentals in CA with mortgages, and 6 single-family rentals in IN.My IRA owns 2 single family rental properties in IN and 1 single-family rental property in OH.None of these properties are currently in a trust or LLC, they are just in our names and the name of my IRA.So far, I've talked to Geico and Foremost since we have dwelling insurance with them. 

I have a brother in law that is young and single.

I can refund your April rent and you can use that for hotel or i can have the garage sealed off and reduce your rent for the loss of area.I have a freshly updated 1 bedroom single family house that i haven't listed yet.

I cannot sell it as-is to a conventional buyer currently because it is a duplex in a single family zone. 

Single family, multi-family, mobile homes, storage units, etc...

We'll be BRRRR'ing as many Single Family homes as we can handle and I am eternally grateful to the BiggerPockets community as a freaking awesome resource!

A lot will depend on what type of real estate you want to become involved with; rentals, flips, wholesaling, brrr, singles, multi-family, commercial, etc.Here are a few suggestions:  (especially for singles and small multi-family)  concentrate on the best school district, get the worst house on a great block, stop your car and get our and actually speak to people working on their yard or just sitting on their porch, eat at a local mom/pop coffee shop--sit at the counter and speak to the waitress and customers.
