Does resent comparable sales impact office values in same building at all or we only need to look at CAP rates and determine the value based on CAP rates alone?

I will reinvest all of the funds from the anticipated 600K sale (less 35K in selling costs).

Junior goes to sale, you are successful bidder at sale.

Also, the day after the sale the IRS will want their cut, or you may have a penalty for failure to pay estimated tax.

It's going to be a money soak and large loss because it seems like the principal wants to outsource eyes, ears, and skills and is willing to pay someone else to bring their own people which costs 2-4x as much as having some of your subs and eyes on the job.If I had other pressing business concerns, I would sell all of the properties in a portfolio sale, bank the money and repurpose it, and let someone else do it all.

Good sales techniques accommodate the customer. 

(Doing your homework ahead of time will have another benefit in that it will make your possible sale/1031 exchange much more smooth if you don't have to fight the 45-day deadline to find new property)

I've been searching online to try and figure it out, but a crime map will only tell you so much. 

However, since I'm kind of an accidental landlord, Im not sure if I should hold or sale.

Current interest rates are going to make it difficult to reinvest into real estate and not come out of pocket more than $1000 annually, per your current situation.I am also assuming you are paying a property manager with your current figures.
