I am responsible for designing HVAC/plumbing systems for commercial buildings.

Although if you are potentially moving in the next 3-6 months then that might not be the wisest strategy. 

I feel the best strategy is to work backwards and start with the purchase to see if it’s even feasible.

This strategy improves cash flow, allowing more freedom in financial planning and personal spending.

For you, if you’re making great money and you’ve already sold your home, I imagine that you will be looking at top home prices, which makes it even more sense to do one of these strategies, because most higher priced homes are the ones comes with higher mortgages and a 1/4 reduction in rate makes an impactful savings.

the book in the bp bookstore. i did the rookie boot camp 2y ago that i imagine this book is kind of based around, and one of the first steps was picking your strategy. the tough part is: THEY ALL WORK. but they all require different skill sets, different amounts of time, and will create a different-looking life for you once the ball is rolling. you have to lay out what skills you have, what you do and don't like doing, how much time you have, and what your vision is for your investor-life 5y down the line, and choose the strategy that aligns best with those things. 

Based on your portfolio design you can find a cashflow or appreciation small multifamily or several single family.
