Cross border taxation is very complicated, most developed countries like the US and Canada have sophisticated systems to ensure their residents pay taxes, and you are not likely to be able to achieve your goal of not paying Canadian taxes on Florida income while a Canadian resident. 

In most Ohio markets, investors can achieve solid cashflow with much lower initial capital investment.

For me, I'd rather have fewer doors owned outright that allow me to achieve my personal financial goals than having a large number of doors fully leveraged with less cash flow per door.

At the time there were limited 3 BR rentals in the neighborhood, but achieved such high rental rates the properties ended up performing better as rentals than as a for sale project.

There are multiple strategies that you can use on mobile homes to achieve your real estate investing goals. 

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

What will you do differently to achieve that goal?

Congrats on buying your first investment property—that’s a big achievement!

Renovation costs would need to be financed separately.Private Lending or Hard Money: Use a private or hard money loan to acquire and rehab the property, then refinance into a joint long-term loan.Seller Financing: Negotiate terms directly with the seller for a flexible financing arrangement.Final ThoughtsUsing an FHA 203(k) loan for your first property is a smart move, and with the right partnership agreement, you can still achieve your 50/50 goals.

First, it is necessary to achieve favorable financing terms and  secondly, I do believe cash flow should carry most rental properties with limited exceptions.
