What kind of ROI i should look at, considering project completion will be 3 years roughly?

Possibly lower returns than projected because of statutorily mandated interest rates following court judgements.

From there determining what you have budgeted for your first project.

There's also huge development projects, many spearheaded by Dan Gilbert's Bedrock investment company. 

as a flipper, with the participation of a wholesaler and a hard money lender, what actions should I take BEFORE I close and buy a house (tell me step by step please because i dont really understand the sequence of events) and also please tell me when to do due diligence to make sure how much does it cost to renovate the house and is it worth buying this house?

We are renovating it as it needs work.

More than likely the PM wasn't aware of the costs as most PM's don't understand project management.

I like Columbus because that's where all the growth is projected in the next few years.

Unfortunately - my current lot for my primary is 1 acre and VERY sloped, and close to a water source (creek), so the county has not even allowed me to permit my downstairs finished basement without an extremely costly renovation to our septic (over $60,000, and that doesn't count demo'ing and replacing our driveway to get to the existing tank and leachfield), and even if I could permit it, it would essentially need to be a treehouse in the redwoods due to the slope (not a bad idea though, I would actually love a livable treehouse on this lot!

I insured a residential property that we are renovating with Obie.
