This is how I grew my real estate business over the past few years.

Even if you create a non-CA LLC, if you are managing the business from California, you will likely be deemed to be "doing business" in California and therefore likely subject to CA taxes.

If a HELOC isn’t an option, alternatives like a home equity loan, business line of credit, or a DSCR loan could work depending on your situation.

If you do that once it's a problem but six times and perhaps more you probably shouldn't be in this business. 

Its not personal, its business. 

Zillow lost so much money that they decided to exit the flipping business, while most of the OpenDoor properties we see in Las Vegas are sold at a loss.In my experience, software can only go so far when humans are involved.

Everything seemed great until the HOA implemented a cap on rental properties due to complaints about absentee landlord's.

Ultimately, you will need to have the borrowed funds in USD and ideally in your US business entity bank account to sail through underwriting with US lenders on US properties.Caveat: the rates will likely be something like 10-12% so it would not make sense on a long-term holding, more like on a down payment on a purchase and rehab value-add project that you will eventually sell (or cash-out refinance) to pay off the borrowed funds in a few months. 

Some of our deals took 1 to 3 years or more but when we landed them ( being that timber is a high profit business) these were 6 figure net deals..

If it’s multifamily, I’ve been in the business for 20 years and can share some insights.
