I wouldn't be selling in this market personally, so if you don't sell the SFR and you really want to do this, a DSCR cash out refinance on the triplex, or a hard money 2nd is your only option to get the liquidity needed to make this move.

Funny thing is that the agent saw how much I liked it and tried to buy it herself but then last minute her money fell through so she came back to me and I had 2 weeks to buy it before probate got involved.

Looking out for suggestions @Kaushik SarkarIf the equity in your properties is your only source for new investing, and the new property you are buying still cash-flow's with the cost of your borrowed money (from your properties), there is no reason to not use it as an investment vehicle.  

They are free to sell their cryptocurrency and then use that money as try downpayment. 

So ask yourself, how much money do you have to invest.  

definitely can get a no income driven hard money style ground up construction loan covering 50% of land and 100% of construction 

The full deal really has very little money into it. (20k) and should cashflow 2200mth with the current tenants.

The years of buying cashflow with zero money are also over.

You are in way over your head if you haven't figured out any way to accept money other than from a money order in the mail.

Consider the time, effort, and expense to develop a concept plan to include site drawings, home types, homes per acre, site storm water retention plan, tree save areas, conservation areas, wetland setbacks, time considerations for meetings with county land use planners, negotiating easements for utilities, rezoning meetings with county council, revisions to your plans to meet demands of neighbors, planners and/or county council, and hopefully getting a final approval for your project.
