If it was still my primary I'd be closer to 1% range. 

I am looking to use the HELOC to take the equity from my primary residence and use it as a down payment for an investment property.

I cash out refinanced my primary in 2019 right at the start of lockdowns with the idea of buying a new home and rent my current.

If you're selling your primary residence then you must have lived in the property for 2 out of the previous 5 years. 

Planning to sell two investment properties in CA and buy one primary residence in CA.Property 1 is listed and expected to sell in August to September timeframe (Around 150K long term profit, total sale price around 0.85M, no loan)Property 2 is under renovation and expected to be listed in August-September, and close around October to November (around 400K long term profit, total sale price around 1.7 M, around 0.6M loan. ~1.1 M in cash).What is the best time to buy the replacement property?

On my primary property, I have a second home that I’ve had as a long term rental and currently have as a short term rental.

I'm considering doing this with our primary residence in La Mesa when we move out of the home, but I want to connect with experts in the area who are already doing this.

And Argentina already is a primary source of investment in Paraguay real estate so no need to verify that.

We recently did the same thing with our primary house.

In most places you can only do work requiring a building permit if it is your primary residence or unless you are a licensed and insured contractor.
