However, Opportunity Zone investments require careful structuring to ensure compliance.Evaluate your priorities: If starting a business is the main goal, proceeds from your primary residence (with the capital gains exclusion) might provide the simplest funding option.This post does not create a CPA-Client relationship.

I've read BiggerPockets' Real Estate Investing book and am particularly interested in the house hacking strategy, as I'd like to move out of my current living situation.Our main dilemma is choosing between a single-family home (renting out one room to a close friend) or a multifamily property like a duplex or triplex.

As long as the property cash flows, that's what is mainly needed. 

The main reason is that it is not initially set up for a Real Estate business like other “real estate-specific” accounting software.

But from my understanding, the captial gains exclusion has two main criterias - you must have owned the home in the last 2 to 5 years and must have lived in the home in the last 2 to 5 years.

Try to make sure main photo very inviting so you stand apart from other listings.

The strategy I'm following for my first house hack is to acquire a multifamily property (duplex, triplex, quadplex) or SFH w/ an ADU (or potential for an ADU) as I am mainly looking to simultaneously acquire my first property and subsidize my mortgage payment.

They said it’s way too small for the price. (3,192 square foot total) 2,200 on the main floor alone.

My main goal is it be able to retire at age 40 from my main job and work entirely on my real estate portfolio.
