@Mike Imbriglio you can ignore what I'm telling you and figure it out on your own but I'd wager they want at least $575k for the house if it is worth what you say it is. 

I am getting coc's of 15 % on preliminary analysis on rental calculator after putting in CAP of 10%. is there a catch ??

Both offsite and onsite.I have reached out to the utility companies, but they are not very open to preliminary discussion/guidance since I only have a TTM.  

In my first month of analyzing properties on the MLS, I've been having trouble figuring out a preliminary estimate for capex and potential repairs without actually seeing the property.

We visited two impressive systems in Germany, but after our preliminary design submittal it was determined that the construction costs alone could not justified.My BIL sent me a video of one in Dubai he visited that delivers the owners Lambo's etc to the outside balcony of their high rise condo.

@Melanie Hartmann, No matter the term you use to describe what you expect something to sell for, that term  will always be an imaginary/preliminary figure. 

Here's a high-level look at some of the preliminary numbers:Offer price: $53,500Purchase closing costs: $1,200Rehab estimate: $25,000Estimated holding costs: $2,000ARV: $105,000-110,000Target 75% cash-out amount: $79,000 - $82,500As you can see, the numbers looked pretty good up front and it looked like we would be pretty close to breaking even on the project after the cash-out refi, so we went ahead with the purchase.

@Brian Wagers Thanks so much for your recommendation, I'll check them out!

Richfield has been undergoing big upgrades - I would wager there will be another mass transit line going there in the next 10 years, and any western suburbs seem to be always very attractive to live.

We have submitted preliminary master plans to the city which will allow me to develop 11 duplex buildings/ 22 units.
