I tend to agree that selling seems like a good option, especially since your rental income will not give you a good yield on current property valuation.Did you live in the rental as primary before?

All depends on the interest rate on the primary home and if fixed.

It won't break down and doesn't take fuel. 

Sometimes we see large amount of equity in a primary residence that can be borrowed against, even in 2nd position if it has a great rate that you don't want to lose.  

In Las Vegas they decided it has to be away form others, have sound monitoring equipment, ban parties, AND it has to be your primary home that you live in WHILE it’s rented out .

I am just starting my investment journey, so have only used Real Estate Agents to assist with buying and selling my primary residence. 

Make sure you have filed for Homestead exemption at the very least (this can only be done if you the home is your primary residence, not an investment home).

If you have not flipped a home, do not have a rental property, and do not own a primary residence, you may have a hard time getting into lending.

Starting out, I would try to take equity from your primary/another property using a HELOC, borrower against a 401k/retirement account, or partner with someone that has cash. 

It's going to be more about your confidence in the market that you can afford than anything else, so the primary thing is to look up a few areas you might be able to afford and then look for someone local that can hop on a call to give you an idea about what investing there is like.
