Inherently the steps are the same as if you were purchasing with financing save potentially less closing costs and ability to close sooner (if needed).The terms of your offer (ie -contingencies, closing cost splits etc) will determine what is different.

Ended up partnering with my parents 50/50 and actually was able to buy two properties the same month.

Is real estate wholesaling a realistic way to start up my real estate journey, and if so, how can I get started in this field?""

In Spain, this is usually seen more as a barrier as people rather would invest in individual units (less purchase capacity needed), but by rethinking the setup up it matches the criteria of a multi-family deal.

One of the first deals I had (multi in an up and coming area) my buyer was paying cash and the deal was solid.  

When it comes to investors specifically, I recommend attending any and all real estate meat ups.

@Cameron Husom I have a list of meets up that I attend along with a list of local wholesalers in the DFW area.
