I find data on free sites like Zillow extremely helpful for days on market for certain homes, and it allows you to sort by bedrooms to see how long a potential property may sit on the market at this moment (great for comping rent prices in the area as well)if I were to live in the property, I would take advantage of the FHA low down payment option to keep cash in my pocket for Reno costs  Hope this helps!
