I don't think enough people consider this aspect.Selling Stock: Selling part of your portfolio could work, but the 15% capital gains tax might make this an expensive choice unless the stock has underperformed or you’re diversifying away from riskier investments.HELOC: Using a HELOC on an existing property is a flexible and relatively low-cost option.

You'll have more flexibility with non-traditional lenders, traditional will all follow the same Fannie/Freddie guidelines.

If I was not starting from scratch, like I did myself, I would buy SFHs because I prefer their long-term flexibility, relative scarcity, and multiple exit strategies to MFH.

I love the flexibility. 

.- My advice; however, is to work with a good mortgage broker as they often have access to more lenders (B or C lenders) that might be more flexible than the 5 big banks.- Finally where to buy: in general, ON, BC are expensive while AB, QC follows and other provinces, such NB, NS, PEI are much much more affordable.

However, they are not as flexible as Fannie, Freddie and FHA.

Flexibility is key for me as I navigate opportunities and continue learning.I’d love to hear any advice you might have or discuss potential opportunities if you’re working on something similar.

Additionally, the fact you might be negative cash flow in Texas will give you more flexibility by renting in Portland.  

If you’re able to stay flexible and learn as you go, I’m sure you’ll gain valuable insights and make progress toward your goals.

I’d recommend shopping around with different DSCR lenders and considering lenders who specialize in investment properties for more flexible terms and options.Good luck with your investing journey!
