Their auto-categorization is also rock-solid. 

The RE market around the country is built to succeed, especially in the Rock County, Wisconsin market.

It turns red if the date is more than 2 weeks old reminding me (in case I forgot to add a reminder) to call the person.

So $1,200 appraisal would be a red flag for me in itself.

For example we write exclusive use of the rental property includes use on two sides to the tree line, on one side to the rock wall and to the front curb. 

It's likely that while the market isn't red-hot, buyers are still willing to pay for the right property.Timing & Interest Rates: You mentioned that you dropped the price after the Fed cut rates, which could have spurred some interest.

Financing either is a bad idea and will raise a red flag with a lender who will look at sources and uses of the loan request.

They all mention that my business plan seems rock solid and they buy into my numbers. 

What are some red flags to avoid? 

That's just my $.02 but I'm sure others have been operating differently with success.As for neighborhoods, West Side, South Buffalo, Kaisertown, decent sections of Black Rock and Riverside, pockets of North Buffalo, maybe some sections of Cheektowaga are going to fall into those categories.
