A house hack for a primary residence for about two years and then you could repeat this again. 

Pay attention to whether the room is a primary suite (your own bathroom) or shared bathroom, how many roommates, etc. as those would factor in to how much someone would be willing to pay.

For your existing primary, you will need to have it leased with the security deposit and first month's rent collected.

A little more about the situation: I bought a duplex last year as a first investment property / primary residence.

Start with your primary, rent out any spare bedrooms "house hack"Use that to practice upgrades, kitchen, bathroom, curb appeal... etcNow you have experience as a landlord and flipper, use that to buy a distressed propertyAdd 40% equity to the property through home makeover, refinance into a low cost mortgageNow you are cashflowing a healthy margin on a second property, use that to build equity over time, cashout later and buy your duplex/quad.If it's going to take you 10 years to save up a down payment for a small apartment building, yeah it makes more sense to start growing your portfolio with cheap SFR flips instead.Every market is different, every borrower is different, every property is different, it would be ill-advised to recommend anything without recognizing the individual's nuanced goals and objectives with their next acquisition.

Living in one unit and renting out the other helps you scale quickly because you need a lower down payment for a primary residence. 

I recently took out a Heloc on my primary home to do a repair and consolidate some debt.

Naturally my DTI is high, however my only debt is our primary residence mortgage I have had since 2020.

I feel so fortunate to have found BiggerPockets, as it’s been a goldmine of information and resources.Currently, I’m leaning towards the BRRRR strategy as my primary niche.

If married you can exclude $250,000 each in capital gains if your primary residence.
