Now you might be like Joe, know rents for a couple of neighborhoods and can quickly estimate expected cash flow from properties pretty quickly (that's what I do as well) but you still need a screening rule so you invest minimal times on properties you will never put an offer in on. 

My biggest two cents is no one should flip unless they are the best at estimating ARV in their room--better than the appraiser, agent, lender--when that happens, your deals will fall into line. 

I just trying to estimate how long it will take the the heaving to settle once I repair the leaks so I can start rehabing the house.   

"In a 2016 paper, Mark Zandi, chief economist at Moody’s Analytics, estimated that full privatization of Fannie and Freddie would cost the typical American taking out a new mortgage $1,200 annually.

I bought the property at $365k, and its new *estimated* value after renovations is 390k-400k.

Is there a place where I can type in the address of the properties I am considering, and it will spit out an estimated monthly rent? 

Cashflow – the numbers look good and give me leeway if I have underestimated renovation costs, over estimated rental income achievable or make other mistakes I am not aware of yet!

Estimated about $25,000 including utility hookups.  

Quote from @Charles Evans: There are websites that estimate market rent, but they can be off quite a bit.

I estimate my rehab costs based on work that I'm always doing in my portfolio or the past flips.
