As you get closer to heavier population it seems more regulated. 

I have talked to a few guru's but everybody wants to buy existing buildings (and rehab them) , not build.

I don't think there is a lot of regulation on what ls legal for transient occupancy, but typically if it's not considered safe for a tenant, it's also not safe for an Airbnb guest.

Thanks for the quick and thorough reply, sounds like you're well versed in the field.As far as possible issues: Are there any special categories for s8 that don't exist for standard SFH rentals that I should look out for?

I have another property that needs extensive rehab and there are a few inherited tenants that would not pass our regulations for screening from what I've gathered so far.

Building a new house on that lot will cost more than buying an existing house that needs renovation.

but you sure see those that live in mid west markets advertising on the coasts for buyers because they don't have enough local buyers to buy the existing inventory..

Great realtor to back into values2. builders to get idea of vertical sq ft costs3. land planner/ engineer for the city county state permitting process.So I find out the big rocks.. then hone in a property that seems good.put it into contract .. then I hire a consulting engineer land planner to do a feasablity study.. if your an existing bigger client they usually do them for free .. in exchange to get your work.but most likely you will have to pay for it.. 5 to 10k is what you can expect.this will include what needs to be done for regulatory approvals.will include environmental hurdles IE who you have to hire / do yo need a wetlands study etc.basic take off on infrastructure costs..

Brokers have the ability to stop syndicating their listings to Trulia and Zillow and other third-party sites with a simple click of a mouse.My brokerage, Hub Edge Realty, has never syndicated its listings to any third-party sites except Realtor.com, because Hub Edge Realty's MLS, MLS PIN, has a pre-existing agreement with Realtor.com, and MLS PIN Homes, because it's MLS PIN's own search site and is not bedraggled with competitors' advertisements.

If I put my rental property in the existing business LLC, Im thinking I could use that income immediately to help get approved for future property purchases.
