There is an excellent book on the subject of becoming wealthy without the benefit of a high paying job or inheritance.

Those persons being, RE attorney, accountant, inspector, anyone else who you've had excellent experience with.

I am partnered with excellent realtor in that area. 

Excellent question, Larmon!

(I already know about maintenance costs, etc. but the property is in excellent condition.)

I get the combination smoke/CO detectors in one unit; if battery-only powered, I get the units that have a 10 year battery and warranty these days.A level of 500 is more like 100 times normal; in a house where I have a CO detector with digital readout and peak level memory, it never got above 9 over many years of service.Sounds like some of that work was not done to code; the code enforcement inspector could be called in to do what they do.

Excellent distinction!

For instance, I have a 40 unit investment purchased with seller financing- the cap rate is around 6% (seller Financed properties have inflated prices hence the lower cap rate), the cash flow is in healthy 5 digits;So still a great investment given the nature of non-institutional debt and the great cash-flow.We specialize in off-market deals & what we teach our clients is to not get stuck in cookie-cutter calculations but evaluate each deal in its own merit.

You certainy have received excellent feed back.

Great interview with some excellent information.
