How do you determine market rent.....when there are no comps?

[Edward Smith]

Hello all. This may seem like a silly question but I thought I'd ask. I have a 4 bed 2 bath 1500 plus sqft 2 car garage all appliances included home that I want to rent out. I usually have a pretty good idea on what I can get for rent by checking zillow and craigslist along with rent-o-meter. The unit is in a B neighborhood but the closest comps are A's and A plus or C-D areas. In a 5 mile range the highest rents for $4700. and the lowest is $1100 the sample size is about 6 properties. I'm thinking $1600-1700.00 is a solid number. This unit is in Milwaukee/Tosa area. All feed back welcome.
