I keep portable AC units for tenants to borrow, so are using one of those to cool the bedroom.I have at least 20 trees down at one property with land and they missed the house but landed on my storage building. 

Hire a property manager.

Hey, I recently bought my first rental property in Polk County it doesn’t cash flow enough for me to have a property manager so I would have to manage this myself for the time being, however in about 6 months I would want to get a HELOC on the property and use that as a down payment on maybe a multi family and then rinse and repeat, I was wondering if this sounds reasonable or would I have to do something else thank you so much 

But Doorloop is $49/mo, $600/yr whether you have 1 property or 100.

Long story short, so now I will be back to square one where I will be renting without owning any properties.  

In this case, I've been a real estate investor and property manager for 18 years so I would be the one to find the properties.

Quote from @Landon Lehmann: If you cash out equity in a property, you are "borrowing" that money from the lender.

My property is in Denton County in Texas.

Your VA loan may allow you to do that and buy more properties at the same time, but you want to learn from your house hack first instead of trying to manage from out of the country.

There used to be loans available for investment property that were 75% where the lender allowed a 15% second.
