.- We have busy but well paying jobs and don't like to spend time in building sweat equity (BRRR, flip), so will take a slightly low maintenance approach and buy relatively newer properties in B class neighborhoods and use property management for day-to-day operations.Goal:- To get to $10K/month net profits with real-estate (today's currency) in 15 years when we plan to retire.

It's also worth mentioning that I already have a good relationship with a wholesaler in town who knows other good contacts, and I am able to use some of these contacts as good resources for general knowledge and learning how it all works.I recently had to close my business of 9 years, and so instead of getting a W2 job or start some other "normal" business, I'd much rather prefer to have house flipping be my primary source of income. 

What does their tech stack look like?

Lesson learned - do a better job screening your tenants...Consider investing in greener pastures (landlord-friendly states)

I was hoping to get some shared insights into what the best starter tech stack looks like for a wholesaling operation.

.: Quote from @V.G Jason: Great job.

Lots of building going on, and lots of jobs. 

Based on the photos we wouldn't recommend a full paint job.

My wife and I both have decent paying jobs, but after paying rent, vehicles, student loans, etc, there’s not much left over for saving, let alone 20% down.

Do you have a nice amount saved up for the activities you enjoy(I assume yes given a 30+ year in Tech plus you mentioning making lots of money already in real estate).If that is the case, what are you looking to achieve now within real estate?
