Even if you do nothing with it, at least you have it and the sooner you act the better.  

Going to jump in sooner than later after a prop in the upper Midwest closes .. serious revitalization going on and some big appreciation

Plus, the sooner they sell the property (no matter the price), the sooner they earn the commission.

While paying down the mortgage sooner has its merits, it's crucial to weigh this against alternative investment opportunities.Regarding upgrading to a property with better cash flow/appreciation potential, it's challenging to surpass the cash flow of a quadruplex unless venturing into commercial assets.

So if a draw is late, or I need it sooner, I have a reserve set aside.
