Looking at a deal where the insurance on the building and flood insurance are identical, doubling that cost of insurance per year.

Yes, premium over SFH given extra work for income analysis and rent survey verification, however, that fee is relatively steep in my experience for a 3 unit. 

No need for tax returns, Verification of Employment, or income.

They look identical.

The dollar return on this one deal didn't change.If you can invest your remaining $75k cash in three identical deals that return $10k each, you will make a total of $40k with your $100k investment, or a 40% ROI.

Low and behold the house next door had been sold in 2012, its street number was only 4 digits different (as in 8523 for subject property and 8527 for alleged house next door)Then I looked at the description of the sold comp and it was identical to the description of the property detail listed on my subject property.Current situation, it appears that that house became an REO and the bank or a 3rd party investor is now receiving rent payments from a tenant who has lived there for at least a year.

Buildium has way too many unnecessary features at a cost until you have at least 25-50 units.I like Zillow for background, credit, income verification because applicants can pay for it all up front and before you even show the property to someone and waste time you already know if they are qualified or not.

I would ask for verification on the payments made hopefully the previous owner was using a service like cozy or rentReady that will easily show you. 

@Bob HinesYour post introduces some very distinct perspective to this discussion, especially with the clarity on the histroy of STL......The 2 STLs (City and county), do they have identical/similar markets?

Right.When you are buying for rental, you have to do 1,000 verification and this should be number one on your number list.For me if I buy a condo, I call their HOA officer and ask this specific question.
