Again, I do not want buying the multi-family home to block me from accessing lending for the second home when I move.- Does anyone see any flaws or can offer some improvements/considerations to the financing strategy of this plan? 

I buy and sell real estate notes.

Well, a lot of life happened and now I am getting back to zero no debt and I'll be renting for now and I am considering a duplex to buy cash or maybe land and some sort of unconventional home but still purchasing cash.

Buy something else.

Are you looking to buy a duplex for your house hack?

Please see the rough numbers below :Tear down house price 350k,Construction cost 165 sqft * 2 build=627k too much for the land unless your exit is 3 million. don't reinvent the wheel. no single family home builder is paying 300k for land. that's miami florida prices where I live. we buy land 50k and under in Columbus Ohio. keep land at less than 10% of after built value.

I can't buy gas with a percentage.

However I have a contractor who I’m considering partnering with who wants to buy and flip homes in Baltimore.

Just make sure you are fluid with this info on each property so you do not buy wrong.
