They help you establish your bankroll and teach important lessons about building relationships and evaluating deals.You may be thinking, "It was so hard to find this first deal.

My point is sandwich l/o are fraught with risk, you need to have a bank roll fat enough to cover evictions, they are just tenants until they buy, and enough time with the seller to get a new buyer if the term ends and they dont close.

The guy is loaded and ready to bankroll.

So you will be bankrolling the difference, most likely.From a personal finance perspective: What about this 'building up credit' plan has to be accomplished via home ownership? 

I earned the money to bankroll it all in my high-paying profession.

But if we're talking to someone with enough cash to bankroll a project, it's would be better than taking a loan--saving the interest.

I'm also working a 40 hour/week job, so if I manage to get tenants in the house for rent I'll be able to bankroll all of the rental profits along with all of the income I get from my day job, which will speed up the process of buying and renting out properties while minimizing the amount of risk that I am taking on. 

-Is it even possible to start with 1K bank roll and possibly attack lands as residential seems out of reach?

I needed a job because it is significantly easier to get financing, and bankroll real estate investing when you have $ coming in.

Some might have the patience and bankroll for those shenanigans, but I don't. haha
