After that my company decided to open suburban remote offices on LI, Westchester and NJ to lessen concentration of workers in 1 single location. 

Both properties have the tenants growing cannabis growing in them. 

I'm trying to figure out whether I just need to concentrate on paying as much as I can towards the mortgage on my current home now to give myself more equity (and more cash flow more quickly once I rent it out), or to be saving that money for the down payment on a tract of land and our forever home while making only the minimum payment on my current home in order to save more capital?

Well-located, affordable real estate is always in demand.If you are truly concerned about Boomers selling and moving, you should concentrate on markets that cater to Boomers.  

I see a lot of your properties listed in PA are concentrated there. 

So we will concentrate on Cash Flow and Mortgage Paydown.In Column D and E, we buy a $1 Million Class B property with a Mortgage of $800k.You will spend about half the hours in Class B as you do in Class D.

Don't bother about the little items but concentrate on the large money items so you know if you want to proceed with the transaction or if you have the opportunity ask the seller to pay for them. 

There is no reason to want to do them....concentrate on other ways to generate buyers and sellers.

Writing ad copy, assembling mail campaigns and face-to-face networking are some of my favorite aspects to the business so I think I'll continue to concentrate there.
