It was my primary residence for two years before I turned it into an investment property.

I'm wondering if you can help advise on this situation.My mother currently resides in a property located in Los Angeles County.

We have a single-family residence we own and have lived in for a number of years.

I've got about $525K in equity in the property, but lenders have told me that I cannot get a HELOC to access that equity for additional purchases because the duplex was financed as an investment - they have said TX law dictates that HELOC can only be used on primary residences.

Investment Info:Single-family residence buy & hold investment.

I started my career with the renovations team renovating the houses we buy, and with the property management company working with our residents and our maintenance teams.

Quote from @Andrew White: Investment Info:Single-family residence buy & hold investment in San Antonio.

I'm going to exclude my personal residence from this because I don't view this as an investment, I need a place to live.Excluding my primary residence my current breakdown is 47% real estate 53% stocks/cash. 

The service providers RTR referred me to were happy to work with me even though I don’t have a US residence.

This defers capital gains and depreciation recapture taxes on the sale of your fourplex.After converting it into your primary residence, you may qualify for the primary residence capital gains exclusion ($250K single/$500K married), but only for appreciation after the conversion; gains from the rental period remain taxable.
