THat's easier to do than you might think: there are 42,000 zip codes, so there are a few hundred thousand people who are "top 5" at any given zip code.Hats off to you for starting to connect with an agent, but I'd wait to buy anything for at least 6-12 months as you build market familiarity!

Make sure your contractors are familiar with FHA guidelines, section 8 inspections, & the housing authority inspectors.

Furthermore, based on it's location alone, this property could be sold to a developer because of the unique zoning that has no limit to the building height built on the lot (!!!). 

Please share reading material , getting started guides or books that might help.I am currently based out of the San Francisco Bay area and I am looking to invest within a 2-3 hour driving range.RegardsYour main goal is to understand the market (demographics, traffic volumes et cetra) and understand what makes a good deal (look at what has actually sold and at what price combined with building out a pro formas to understand it).  

PLUS, good property management companies are great to build relationships with; they see and hear of off-market deals.

Plus, it helps me build a good relationship with the seller, which can be handy when it comes time to talk about the price.How I approach the property tour depends on a few things, like how the property is being sold and where it's located.

I am looking for a builder to partner with who will finance building costs (and get reasonable GC fees above cost for their efforts as well).

I am not sure on Florida, but typically Section 8 won't do a full inspection until you have found a tenant for the property.

I have also aquired vacant lots that I plan on building duplexes on...

I think, generally speaking, this is one of the bigger reasons NOT to build an ADU in your backyard simply because you have the space: there aren't really any simple ways to finance the building costs.
