Buyers can eventually turn into private money lenders and JV partners, and they're you're customer so the fact that you have a lot of potential customers calling wanting to be on your list is great, remember that. as far as marketing for sellers I believe the absentee owner list is overused, it's become to common of a target list.

I'd also like to eventually make real estate my full-time gig.

Eventually, I grew to hate it.

I want to invest in buy-and-hold in single family, multi family and eventually apartment complexes.

Eventually left engineering (not due to financial freedom, but everything related to it- lifestyle design, business-building, investing in passive income properties, etc.).You're going to have a blast, that's for sure!

My wife and I are both US citizens (from Columbus, OH) and would eventually like to look into buying investment property there.

This yang approach will eventually get there but why not take a more holistic approach to your business now.Surely, it is sad to make millions of dollars and burn bridges with all of your family, friends, employees and other relationships.

Skill level will eventually increase and conversion rates will rise, but the best focus is quantity in the beginning.Once we get a few deals under contract, we will cherry pick the flips that make the most sense for us based on experience level (what we can confidently handle) and profit margin.  

Right now I am just flipping contracts as a wholesaler and wanted to open up a company business as I plan on moving into flipping homes and eventually holding properties..."

I appreciate it, and look forward to eventually meeting you.
