I'm at the front end of a marketing push where I'm building a database of 200 addresses in a defined area, with plans to send out a marketing letter to all 200 with hopes of getting one closed deal.

Aloha,Applicable Local, State, and Federal laws could arguably be most important of all to be aware of, to varying degrees, and in many cases, you need significant understanding of particular laws, depending on the specific RE path you are working.City and State LL/Tenant laws; Fair Credit Reporting Act; Regulation Z; Fair Housing; State/County/City Zoning and Land Use ordinances; Building Codes, Permits and Inspections; FEMA Flood Zones; EPA Regulations including for lead based paint, asbestos, waste water handling, grease traps, underground storage tanks, and septic systems; Life Safety Code NFPA 101; OSHA regulations (apply to all businesses and/or employers); Condo/HOA State laws and individual project Governing Documents; State Real Estate Licensing laws; State Administrative laws for RE and/or other businesses; State and local Tax laws; and likely a few more...For Rentals, the two most critical areas where mistakes are often made, and can be very costly, are the Tenant Application and Screening Process; and the Rental Preparation Process (from acquisition or vacancy, to an approved Tenant application).

The trust manager does but listens to your instructions.Depending on how the funds are disbursed, you should consider placing as much as you legally can into a self directed ROTH IRA for you and another for your spouse.With a self directed IRA you can loan money to other investors with Equity Trust as a third party administrator and avoid the perils of Tenants and Toilets.

is there only a database for that?

Is like on top of learning the essential on how to negotiate, comp accordingly , Manage you crew hire ( if you are going to flip) or if you wholesaling , (finding investor, creating that pipeline) , now you have to add, systems, lead generation, branding , administration  etc etc..By the way we buy ugly houses is a DBA of Homevestors, they have been around for a while. and is one of the few companies that offer that model.. 

So, to use the LLC correctly adds some to a good deal of extra costs and administrative headache. 

I think with the current administration, that's certainly within the realm of possibility.

I use an investor qualification form that collects name, contact information, accredited investor status, and amount the investor is seeking to invest.It's a good idea to maintain a database of your investors that includes the date of first contact, the date you gave them your credibility package, the date they returned it to you, how much they want to invest, etc.  

I don't have reason to suspect anything until I pull credit and the "AKA" names and past addresses make no sense ("Julio" having an AKA of "Jessica," he told me he's always lived in CA but the credit report has a bunch of Alabama addresses on it and only 1 CA address, etc), and I don't know for sure until this form comes back from the Social Security Administration - https://www.ssa.gov/forms/ssa-89.pdf / https://www.ssa.gov/forms/ssa-89-sp.pdf

I've searched podcast data bases and found a few, but none so far that deal with only landlord/tenant issues.
