You are in a great situation being ambitious, young, single, no kids, and flexible ... yes, starting out is very difficult as it can take years before you start to see the fruits of your hard work, especially before you lock down your first investments; just have to keep at it and have faith that your hard work will pay off in the long haul, so long as you keep at it.You mentioned sales ...

I spent about a decade working my *** off, getting ahead, and now I'm enjoying the fruit of those labors.Here's my two cents: don't buy a condo.

You haven't spent one extra dollar that you were not planning to direct to early paydown anyway, but you get the fruit of your labor earlier and I think it makes more sense if you are planning to stop the w2 job relatively young.  

That was low hanging fruit.

Later on, as you have acquired more, I would lean back a bit and enjoy the fruits of your labor.

Do you want all your eggs in one basket or spread out over many.

I want to be heavier in real estate, but I don't want to have all my eggs in one basket, as they say.

Socialism has no fruit w/o its latent social defects.  

Yes it is easier but it is low hanging fruit

This way, you're not putting all your eggs in one basket.
