If you want to flip or do more short term projects, then a HELOC may be a good idea if you can find a lender for that and you can keep your likely low rate.

I've decided that I want to manage it myself for at least a year to not only save costs but because the property is local to my next one, I've lived in it for over a year so I know the maintenance of the home, and I'm a PM for a home builder so I have all the handyman/tradesmen relationships that I can use for any repairs.

On the other hand, a cash-out refinance of your current duplex is another avenue to explore, albeit with considerations such as the risk of losing your low 3.5% interest rate and increasing your loan amount and monthly payment, thereby reducing your current positive cash flow.

Thanks @Bradley Buxton and @Bonnie Low!

Moreover, while there is currently a lot of hype around seller financing and low and no money-down investment strategies, the reality is you need capital to be a player in the space.

Some context would really help, i.e. are we talking about commercial zoned land or residential zoned land, and if we are talking about residential land, are we talking about low density/agricultural or land where you could put an SFR tract or row townhomes or even a dense apartment/condo project?

For a rental, I would just use off-the-shelf cabinets like those at Home Depot or Lowes.

Quote from @Bonnie Low: Being able to pivot is crucial and it's great that you had multiple strategies available.
