IMO, a CPA is worth their weight in salt!

What we generally due is instead of looking at an investment from a cost of capital or weighted cost of capital basis is to use a hurdle rate, an interest rate at which we demand a specific return.

I need to know which factor is most important so I can add a "weight" to it. 

I wouldn't put too much weight on dollar values as they are more of a scorecard and by themselves aren't useful at all. 

I completely understand if one does not to go Pro, but for me, it is weighted heavily as a time~money decision as well.

@William Hochstedler @Abdul AzeezI'm in agreement with all three of you -- it seems when playing the long game, as I am -- the weight is on leveraging wisely, letting tenants carry that load, and expanding your risk profile across as many properties as you can "afford" to meet your cashflow goals.  

Purchase price:  $33,830.86Acquisition costs (taxes, insurance, inspections, title fees, etc):  $4282.57Holding costs:  $2194.18Rehab costs:  $54,404.23Total invested:  $94,711.84Sales price:  $129,900.00Buyer subsidy:  $7665.03Sellers closing cost:  $8151.95  Total return:  $114,083.02  (plus $1795.86 commission return because I'm licensed)Profit:  $19,371.18 ($21,113.04 if you count the commission return)Not too bad for our first time, and the knowledge we have gained and contacts we have made are worth their weight in gold :)

Each of the characteristics is assigned a weight based on how strong a predictor it is.

The effect is that you have a lot of weight (maybe a couple tons) effectively sitting in the middle of the floor.

Long term leases generally will use weighted averages of cost of capital.
