purchasing through an action - how much to enter the game?

[Tatyana Williams]

good afternoon,

I am new and have perhaps a stupid question. I am  interested in saving up cash (financing might not work for me) and purchase a buy and hold rental in Fairfax, Arlington, or Loudoun county (most likely condo since it would be more viable financially). Based on your experience, how much money do you need to enter the game? Is it realistic to buy anything for 30-40-50K or is it more like a 100K entry point? Thank you, all, so much!
