How did you find this deal and how did you negotiate it?

After talking with some folks, you will find someone out there will have a bunch of cash.

I've noticed that properties with virtual tours tend to get more engagement online, and investors/agents who use them often say they help attract more serious buyers and renters. 

Lots of wholesalers are nothing but contract executors and do nothing but tie up properties without the ability to sell to and end buyer.

You can find one that specializes in STRs. 

The one guy I spoke with said they make money only when they sell to potential investors and they only sell new construction homes that are usually pre-leased to buyers (currently they are building in Texas state and Missouri State).

Purchase price: $990,000 Cash invested: $350,000 Purchased this home with my former partner back in 2018 and we put 200k down.

Unless the property needs work and the seller is desperate, you're not going to find a seller willing to do any sort of seller financing on their end. 

Right now, I'm working with a team that helps find off market properties for investors which has been a great way to dive in and connect with experience professionals in the industry.

You will find that as you add to your portfolio, they get easier to add.
