@Martin Bys pretty basic goals, you'll need more specifics to achieve them!

Attending local real estate meetups can be a great place to find other investors as well and get more market specific advice!

They can help guide you in specific local markets.

I've been saving up for my first property purchase, specifically aiming for a duplex.

That is a pretty loaded question and depends more on the host and the specific property in question. 

I sure won't be popping up to fix a leak so property management will have to be in the budget.

Things may get a little more complicated depending on your specific situation, but that's kind of the general idea.

Get rid of debt, build a budget, and save.

If you find a place that will cash flow at a 200k budget on long term rents in Houston, I promise you that you do not want to own in that neighborhood AND it probably does not actually cash flow due to the class of tenant, capex, vacancy, and turnover costs.I'd suggest you try to find some connection to a place rather than randomly picking a market.

If you can't see certain rooms, like the kitchen, just budget for a complete kitchen.
