Determining Rental Rates

[Daniel Sabato]

Does anyone use any specific websites or programs to determine what rental rates might be in a certain area? For example, I see a 4 bedroom house and I want to figure out what I can rent that out for, which is crucial in my analysis before buying the home. Generally I use zillow, realtor.com, trulia to get a feel for it, and I also try to look for purchases only in my area where I'm familiar with prices and what is normal to charge. Sometimes I see prices that seem super low to me, but I'm also not an expert in the area so it's tough to say. Does anyone have any tricks or anything that they use to figure it out?
