Multifamily here in Co Springs and Denver area has been "overpriced" somewhat because of the military presence and rise in popularity of house hacking. 

Turbo Tenant is a popular one.

Seems like this a pretty popular thing going on across many states.. 

Pull down the listing and see what platforms are popular in your area, then list it there.

do some odd jobs--plenty of contractors are looking for help...start a lawn care business (extremely popular right now), work for a company that's involved with real estate such as a property manager, title company or hard money company (F-Street is often hiring) or a real estate investment company? 

A lot of the popular, no money needed, strategies like being a wholesaler, getting a partner to fund the deal, or STR co-hosting / arbitrage are a bit of a paradox because the people that have the expertise to effectively implement these strategies are typically the experienced folks that don't need no money down strategies to invest.

I bought my rentals in Killeen while at Fort Hood early 2010s, including quadplexes. 2-4 families seem to be especially popular around military installations perhaps?

Do research on what are the most popular for STRs and if there is a missing niche in the area. 

Propstream seems to be very popular and I signed up for an account but I'm confused about what to do once I have a list of leads.

But I'm also of afraid of missing out on a good opportunity to get a townhome in a expensive popular area at the price point and interest rate I find to be favorable.
