There are a spectrum of gurus, it seems.Some gurus are folks who have deep expertise and can teach it to others.

Lot of good areas in Carrollton too.In Irving you get extremes... higher end houses and nicer apartments in the Valley Ranch area (planned development; HQ for Dallas Cowboys), and then you have the area around Beltline and 183, and south of 183 at the other end of the spectrum. 

Landlording wasnt even  in my spectrum. 

The opposite end of the spectrum is buying turnkeys, where everything is done for you so at that point you wouldn't technically ever have to go out, but I'd recommend going out at least once initially and then during any big turnovers.

I was working with Lima One through a 3rd party called Spectrum Funding.

My Military Occupational Specialty (MOS) in the Army is an Electromagnetic Spectrum Manager.  

From what I've read, the housing authority can be anywhere on the spectrum from outright hostile to landlords to being a landlord's best friend with regard to dealing with bad tenants. 

In addition to meetups, Atlanta is constantly having conferences that run the spectrum of retail, SFH, multifamily, office, etc that provide great opportunities as well. 

I tend to go for mortgages on the longer end of the available spectrum too, but as I mentioned in my prior post getting a 30-year fixed rate on large commercial multi-unit properties is difficult to impossible.

When in doubt start towards the higher end of your rental-payment spectrum and lower your price accordingly or for a certain renter.
