Lets compare Memphis to lets say Denver...Memphis Avg Price = $118,467 Avg Rent = $10,906 Maint can CapEx = $1,635 (fixed since heater costs the same in Memphis as it does in Denver as you are saying...)All other expenses = 40% of gross rent = $4,362 (I put expenses at 40% just at random and have the 40% fixed for Denver as well)NOI = $4,909CAP Rate = 4.1%Denver Avg Price = $364,400 Avg Rent = $16,932Maint can CapEx = $1,635All other expenses = 40% of gross rent = $6,772NOI = $8525CAP Rate = 2.3%So it looks like even with you stating that maintenance and cap ex-numbers cost the same from market to market higher rent to value markets do reflect better cash flow invest ability...by nearly being twice as lucrative in terms of cap rate vs cap rate comparison...

I bought one because I am in the mold remediation business and I wanted to see the results compared to my $1,000.00 kit that I purchased a couple decades ago. 

@Alex LandauYou are looking at Morris Invest and then comparing what they sell to the Milwaukee market.

The offer sounds tempting since  the group has to finance about 3M$ (the rest comes from a bank with a low interest) and the building is bought about 1.5M below value, so when we sell we should expect a 50% return when selling which should be 3 years from now.The thing that bugs me is the way the building value was evaluated, i am copying a section from the presentation:"Market activity has shown similar properties consistently trading in the 4.75-5.25% cap range (refer to “Comparables” slide for specifics).

That gave us the option of shifting almost all the building coverage to the Unit Owners and minimizing the Condo owned (common elements). 

Maybe, but this argument is short sighted and doesn’t take into account risk.Despite what most people on here say, REI is one of the more risky investment vehicles as compared to say stocks or bonds (don’t hate me, I love REI too, I just do both).

This seems like actually a decent # but is it compared to what others are seeing?  

However, you should get some quotes and compare the coverage.

A C-corp traditionally has been a poor vehicle for rental real estate but now with a lower 21% tax rate, is becoming a better alternative, especially compared to an LLC which can be taxed as high as a 37% individual rate since LLCs are pass-through entities. 

If a comparable house at a comparable price took 90 days to sell, that's probably what you can expect of yours.
