But have to consider some factors.

@Trent Smith PLEASE factor 3-5%.

One factor you did not mention is your income.

A primary driver is uniformity of community, the next in most cases is connected with our development funding and approval at a regulatory level. next is market factors, for example a certain area that HOA's are the norm or the expected for a certain price point.

My friend/advisor with more experience says I am being a cheap knucklehead and that the $20k is not relative when you factor the forced appreciation and income/valuation of the improved asset(proforma), but, I think it is math and $20k is always relative and I have my criteria(4.5cap) and was very transparent about it from when I first submitted the original accepted offer, and my DD uncovered several hidden deficiencies that make the credit necessary to maintain my original underwriting numbers and even though I understand my friends rationale, I don't want to give in any more slack(adjusted to 4.4cap), than I already have...What do you experienced multi family acquisition people think?

Those numbers, though, depend on many factors that will be specific to your local market; you won't be able to be given a simple yes or no response from anybody here.

I would say if you are stuck on 1 % and nothing less you will most likely be sitting a while, there are lots of other factors that make it worth buying real estate in Clarksville and hitting 1% could just be a few years down the road off of increasing rent rates. 

@Ben Nelson mentioned the sage wisdom of correctly setting team members, that is a whole lot harder today because things are at such a level with so many factors at play and fact is the vast majority simply do not have the resource pool to have a truly well equipped internal team or knowledge base, it is a very small number of us who do. 

I would propose a better way of evaluating real estate and that is to take the difference between the CAP rate and prevailing interest rate and use that to evaluate whether something is a deal or not.D = CAP - %APRThis would allow you to calculate the spread which is directly related to your debt assisted profitability (like a cash on cash return).You can vary what “D” you will accept based on the normal factors you would consider when thinking of the CAP rate (location, building type, number of units, financing, deferred maintenance, etc).You could also rearrange the equation to calculate the CAP to search for opportunities and how to offer for property:CAP = D + %APRIn this case, you can actually figure out the CAP by knowing the “D” you want to get for a given location, building type, etc and understanding the financing available to you and other investors for the opportunity.Any reason this is an inferior approach to CAP rate or cash on cash return?

Lot of factors to consider.
