Best way to find or estimate rent prices

[Dylan Fellows]

I found a property here in Wichita I really like and I’m trying to run the numbers to find my offer price but I have some questions. It’s a duplex right by Lincoln and rock and it meets almost all my criteria. Southeast side, little to no renovations and tenants already renting one side. 

Now I'm not to worried about the ROI numbers this time because I will be using FHA and my initial cash investment will be very low. I've looked at the average rent prices in that area from a Zillow spreadsheet and they look to average at about 980-1000. Looking at those numbers and using them I should be able to cash flow close to 200 a month when all is said and done and hopefully I'm not being to modest with expense numbers. 6% vacancy, 5% repairs and 100 CapEx seeing as how the appliances are almost new. I will be house hacking this property so these would be future cash flow estimates.

If anyone has any information or tips on how to truly estimate rent prices or my percentages for expenses for my analyzing I would appreciate some help. 

Thanks
