However, once I committed to it and viewed it as a business, I was able to achieve FIRE after a couple of years of hustle.

I want to become a multi-family investor to achieve financial freedom.

But that's what investing is.....deploying capital to achieve a return based on risk.

Yeah, we both want to have the tallest buildings, but we don’t have to tear down everyone else’s building to achieve that.

Do you have a family member or friend who's achieved what you want to achieve?

Using the 50% rule (taxes, insurance, Capex, maintenance, vacancies, property-management), that should give us ~19K/month in pre-tax profits that achieves our 10k/month financial goal after-tax and adjusting for inflation.Our assumption is that building new-construction would reduce capex & maintenance the first few years. 

So presuming you are on the "add one rental a year plan" after maybe buying 4 with the money you have, I would think it would take a number of years to achieve that retirement goal - but your mileage could vary depending on how much income you need to live on. 

Highest ROI, especially in markets that appreciate faster than inflation, is achieved at highest leverage.  

And, Side-X-Side is the hardest and rarest layout to achieve when converting from a SFH into a small-multi. 

These options allow them to control expenses better, attract similar tenants, and often achieve higher rents with lower costs.I believe there is a promising market for purpose-built attached single-family homes for rent in Worcester.
