Different asset classes of NNN have varying dynamics with primary lease length term, NNN,NN, or ground lease, down payment percentage, rental increases or not in primary term, cap rate range, typical purchase price range, guarantee level of the tenant  etc.You just need to hop on a call with someone and then take a bunch of notes.

My thought would be he would get 50% of the profit from the percentage of the investment that his $50k buys.

I would think they would get their initial investment plus a certain percentage of the profits after completion of the exit strategy along with monthly or annual compensation taking into account how well the property is performing.

I've seen posts here which explain CR as an apples to apples comparison for a market...if the driving forces (demand etc) are consistent, is the CR variability simply how the sellers are pricing the property?

The really bad molds make up a very small percentage of all molds.You need to investigate the history of your property (was it ever flooded, did a supply line leak, how's the wax seal, etc.)

Here is what I do (without spending any cash on any program):My 1st mortgage is owed on the 1st and not past due until the 16th of each month so I make my first mortgage payment (rate at 5.5% fixed) on the 15th with funds from my HELOC (rate is variable but has been at 4% for quite some time).

CalculationThe main calculation itself is pretty straight forward:Buy-out Cost = 0.5*(FMV-Mortgage)This would take into consideration any built-up equity over time.FMV would be determined from 1 or 2 appraisals OR how much similar units are selling for (if it's a condo being sold).Costs Associated with SellingFor a portion of the cost associated with selling the property (Legal/Bank Fees/Realtor Fees), I've tried to search around and gathered the following FOR/AGAINST arguments for including such fees:FOR including the fees:There should be a 'penalty' for pulling out of a long-term partnership.If the surviving partner sells at some point, he takes the whole portion of the cost himself.AGAINST including the fees:The surviving partner has the option to conduct a For Sale By Owner, or use services such as ComFree, in which case no major realtor percentage fee would be paid.The surviving partner may choose to never sell.The surviving partner would still have a cash-flowing asset that is likely to appreciate.Based off these arguments, I think what might be fair is the normal Buy-out Cost calculation, minus a nominal percentage.

I know the STR gurus push “names don’t matter,” but I find it’s helpful for signage to direct people to your cabin, and some percentage of my guests refer to the name of the cabin when they thank me for their stay.

but job is easily 8 weeks and 9-10 if variables come up..     

I don't deal with averages or percentages as goals or measuring sticks.
