I'm very new to investing and weighing which options would benefit me the most.Option 1:  Use the cash as down payment on another primary residence and rent out the current.

However, required downpayments were typically 40-50%, and would be difficult without a residency visa.

Lots of good advice here, but no one asked what your parent's retirement plans are?

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

One more thing I should address:  Installing cameras inside of a residence with other tenants can be a HUGE legal violation.  

I’m new to REI and plan to invest locally in the Houston market. I am looking to grow my buy and hold rental portfolio and would love to network with other investors/agents/wholesalers etc. Any recommendations on Hous...

We have resided in Miami for 12 years.

HELOCs are fine, but keep in mind that you really only want to use 50 percent of less (each) of your available equity just so you aren't creating a problem that you can't solve later if the value of your personal residences fluctuates.If you both have W2 jobs though, have you looked into getting qualified together and just getting a loan, 10 percent down each?

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

I was preapproved with that amount before, but it was for a single family, primary residence about six months ago.
