Look at their marketing strategy.

@Cole DobbsIn addition, I may be able to help you and connect you with some key real estate investor players in the Houston, Texas market since I am an Investor myself that have done most of these real estate investing strategies and also an investor-broker who has helped over 400 investors like you. 

With $50k, you likely have enough to get started, especially if you target lower-cost markets or use a strategy like house hacking.

What strategy are you most interested in—flipping, BRRRR, wholesaling, or perhaps Airbnb?

My strategy would then be to lease at least two of the renovated units, increasing occupancy to 90%, which could improve the chances of securing favorable terms for refinancing.I haven't pitched it to the seller yet.

Leveraging seller financing creatively, with strategies like stepdown interest rates or unique amortization schedules, could be the key to bridging the gap until the property reaches its full income potential.

If you're considering starting with a duplex using a VA loan, that's a great strategy, especially for house hacking.

What other investment strategies are you looking into? 

Knowing your long-term plans can help you build a long-term financing strategy so that you are not just worried about purchase number 4, but also purchases 5 - 20+ (if you plan to continue to invest).I'm an investor and licensed mortgage broker.

So anyone who advertises or uses ANY marketing technique, can really advance businesses here.
