I'm looking to grow quickly.Do you advise sitting and waiting it out? 

Columbus is rapidly growing, with the population, job market, and growing tech scene driving strong rental demand.

My capital continues to be completely tied up in the property since I'm pretty maxed on my LTV and likely can't unlock any more equity with a HELOC or something like that.The goal of this project was always meant to be a short term exit so I could continue to try and aggressively grow my real estate portfolio, but now it feels like I'm stuck at first based.

For (2), as properties age the rents you command decrease. 

@Daniel Vo, sent you a message but I am proof that you can start in your late 30's and figure this all out while still serving and setting yourself up to grow even more when you retire from the military.

I started at age 20, dead broke with no experience but hungry with lots of time on my hands. 

There are definitely areas where you could repeat a similar strategy but with even better cash flow.If you’re ever looking at growing your portfolio elsewhere, I come across off-market deals that could align with what you’re looking for.

Along with our partnership with GS Courtyard Homes this is a thriving and growing community, located in an amazing market.

It does however give you a degree of independence to choose what you want to do.As your portfolio grows you'll also feel the weight of future capex responsibility more, which ironically points you to growing more cash flow through more real estate.The other issue is that you are chasing a moving goalpost.

My thinking is that there is always room to grow and learn and expand my network.
