I am glad to have been a bit conservative in my approach and deal making.

I factored in property management at 10% as well as capital expenditures, maintenance, sewage, etc.Granted, I am aware that the tenants will likely cover their own utilities; plus I don't live in Vegas, so my estimates may be a lot more conservative than what the actual average amounts might be.

If not it is always best to stay conservative when analyzing deals. 

Find a bank that has a list of appraisers with less conservative pricing (i.e., more aggressive estimates). 

Both of your assumptions above are pretty conservative. 

(Houston, Austin, Fort Worth, New Orleans, Oklahoma City) and learned some "sure fire" ways to garner good, reliable, conservative, numbers for me to base my "comps", no matter where I found myself.Find someone local, who knows the area and works it well.

Investors paying down a rental are the most extreme conservative investors and rarely understand how little their dead equity is actually earning.

I  posted the $650 conservatively since I knew people were paying that in the area.
