If you judge those items to be serious, then you know this tenant has potential for you - if you actually are one of those landlords that performs needed repairs :D ; if the items being complained about seem to you to be more of a nuisance, then it sounds like you wouldn't want that tenant.You might find that a thorough screening (as Joel has given above) uncovers some other reason to not take this person as a tenant - so let your screening process be your guide in decision-making.

What about something in a Cleveland suburb with 25 units that rents for $600/mo per unit, built in the mid 90s, well maintaned, with free wi-fi, good (but uncovered) parking, in-unit laundry?

I felt the need to share that because, like in their voting habits, some people follow crowds, their past experience, or their own flawed logic, rather than doing research.  

In the event the title search due to human error overlooks or does not uncover an existing problem the title insurance will give you some additional protection.

If you have not had to deliver any documents or information about the primary residence loan to the investment property loan, then I suppose my assumption that you qualify for both loans could be flawed.

Line up a Title Company that you feel you will continue to work with and have them do a preliminary search to uncover any liens, judgements or encumberances.

I've had some success but a major flaw in my business model came back to bite me.

If in 2005 it were negligent in its duties as alleged , and was fully aware the suit against them, and then they chose to go forward then that was their choice within the process (not a flaw in the process itself).

However, there are many flaws with it that you should at least be aware of.

long story short it was a foreclosure, under contract to a new buyer for $200,000, who could not settle because of a title flaw that only I could solve.
