You can find comparable sales in 2017 and use that dollar/acre figure to arrive at the fair market value then. 

I was misled when I made my investment, with Dutch frequently stating in public communications that RAD is “like family” and that funds would be returned easily if needed.

You've probably heard of big Landlords losing property, but only because they were flagrantly violating Fair Housing, running a slum, or otherwise violating the law in an egregious manner.

I use standard market PM rates in my underwriting, but I also would not work for those rates but it is fair compensation for the work.I typically use vacancy of 5% not because I have ever had a unit that had that high vacancy but I do not have a no payment category and I want the underwriting to be conservativeon the opposite, your rate is a bit high and your appreciation rate and rent growth are modest.overall, seems like a decent attempt at an analysis.  

I do have a few fair contractors. 

I'm also considering finding a seller that would pay more than me to help my father-in-law out and perhaps get a wholesale commission that I could use on my next (ok, first) brrrr, but I'm not sure the best way to validate a fair price or know what a fair wholesale commission would be.

That's fair.

I'm a fairly new investor and was looking for some advice on what my next move should be if I want to build up a portfolio of STR's.

Is this a fair price for snow removal?

@Zach Lemaster I wish Rent to Retirement would have informed us of the communication issue they had with Delta Build.
