I live in Manhattan and have been studying markets for a few years now.

I'm reading everything I can, listening to podcasts, studying the market, everything I can do.

There is a post laying out great neighborboods to invest in which I have studied, but I am looking for advice on house rental prices or any other kind of advice on where to buy, or any house deals!

If the money you get does not match your efforts, it's time to take a pause and have a further study on how you can correctly make it.House flipping is a step-by-step process.

@Scott Meyers  has a storage academy  that's the one I went to in Vegas this year.. lots of good info there..I would make contact .. your probably on the advanced ( well not probably you are ) advanced side on the development end so it would just be running the numbers.what I saw scott teach though was hiring a consultant for market study in that study will probably answer your questions and you will need it most likely for your debt financing unless your paying cash.

I study the lot now more carefully to assess water flow. 

I am a recent graduate with minor amounts of student loans to my name but I am still in line with my DTI to be under the 36% threshold most lenders look for.I have been studying all aspects of real estate investing for the past 3 years now.

I'm still studying property analysis, but that would be (has been) my reaction to a deal with those numbers.Keep on keepin' on!
