So I created a bunch of cash flow to free me from my job - through a combination of W2 supporting RE, until I could break free.

I think this is mostly a function of stock valuations peaking.

Combine two exchanges, the house and the vacant lot and use the proceeds to buy a completed house on a similar lot (or any other property you would choose).2.

Myself and 1 other heir are able to pay an additional amount of our incomes for a combined total of $3K.

We both just started new jobs and now gross $105,000/yr combined income.  

Those motivations combined with your numbers will get you, or should get you, a number in your head.

Perhaps you can do some sort of combination.

I'd like to have another stream of income in the form of rental properties (possibly flips).  10 yrs ago my Dad & I combined equity lines & put another house on the back of his property in the heart of Roseville, that was an experience.  

More knowledge and inspired action based on the knowledge here on BP is a winning combination.
