I have an opportunity to purchase the MAJORITY of a townhouse complex in Fort Smith, Arkansas but still don't quite understand how to use the analysis calculator to determine if it's a good deal or not.

Run the scenarios for wholesaling versus rehabbing and determine what the profit potential is for each. 

I've already determined the most I should spend would be 160K.

Well-intentioned but informed lawmakers had determined that no lender should ever charge more than 10% for a mortgage loan so they wrote Usury Laws that forbade any higher rate.  

Mind you, there are some properties that are much more expensive and there are some condos that are listed in the area around $155-190k'ish range (built around that 70's-80's range).My question is how to determine how much it would cost to build to completely new properties, and how would those be comped out, as there doesn't appear to be a lot of new builds this area; however, I know of some new builds that are going up in the city next to it, which will be starting in the $450k range, and that's approximately 3-5 miles away; if that.I appreciate any advice you may have.

I had a roof where we replaced 6 shingles and because they had not laid down and adhered to the layers below the inspector determined the roof needed to be replaced.  

So by understanding how much cash flow you need will determine the types of deals you target to purchase.As a CPA I always suggest forming and buying property in an LLC as it gives you flexibility from a tax perspective and also has legal protection.

Works, but the contractor has to be involved (and knowledgeable) in determining ARV/ margins.  

sounds like a good ideaCurrently I am try to determine if CCIM licensing would help in my market.

Not to mention being able to estimate the amount of work needed to determine what the maximum allowable offer should be.
