If you plan to use the remaining HELOC for a DSCR or BRRR strategy, that could help you build more equity, but consider if the current market conditions will lead to higher rates and lower cash flow in the near term.If your goal is to scale, you might consider holding onto your current duplex for the cash flow and focusing on the BRRR/DSCR strategy, which can allow for more control and potentially better long-term returns.

one truism I think for rental real estate is returns and price points are very much risk adjusted highest returns lowest price points  biggest risk.. smaller cap or return and prime location least risk..

Is inflation at risk of reigniting or is the long-term downward trend still intact?

Yes this leaves more money in the deal but it reduces my risk and ensures I can remain profitable in a down market. 

A duplex could be a great compromise that lets you start small, build equity, and learn the ropes while mitigating some of the financial risks.

As for the increase in rental potential on the properties.

But, like everything in lending, when you "risk layer" the rate/terms are usually a little worse.

All have different perspectives in terms STRs and how your neighbors could potentially impact the experience.

@Kevin Bartel If you're starting in real estate investing with a high-paying W2 job and a demanding schedule, your best approach depends on balancing risk, involvement level, and income potential.

So it could take a decade to get to todays market rent. 2) it’s almost impossible if not impossible to non-renew a tenant, especially if you’re not an owner occupant. 3) As a seller, even if I could remove paying tenants I never would without a non-refundable payment from a potential buyer that covers all vacancies for 6 months if they fail to complete the purchase. 4) You MIGHT say as a buyer that’s worth it.
