So, basically you are using the $500k in crypto to secure what would normally be your 20-25% down payment in a normal financed deal.

I see there is also an option for business deposit accounts.

I'm open to properties without septic as compost toilets are an option.  

The monthly payment on our new house would be much lower than if we chose option 2. 

While the purchase price will be used as the "sales price" for appraisal comps in the future, it doesn't mean that the buyer hasn't secured a deal that does have day 1 equity.

Having good processes in place is particularly important for tenant screening, move-ins and move-outs and the handling of security deposits, but I don't know how you can have processes to guard against criminals and unfair government policies like those in place in some areas during the pandemic.

Some things you may want to consider, it is generally a good idea to have a separate lease agreement from the purchase option. 

Second option, if it's even valid, I could build a new house in one of these new communities and then have the house for another few months and sell it (assuming that it would have increased in value) Any input to any of these two strategies would be highly appreciated!

I've also considered forming an S-Corp in PA, as I want to have a self-directed retirement account someday, and it would be easy to max out with the revenue from the PA solar farm.If I had a self-directed account, I would likely do some investing in securities, but most in real estate (likely in NC).

Some of the best spoken words I have ever heard "I also understand that the real money will be made on the 3rd, 4th, 5th+ deals, so my primary concern is getting started, getting experience,"If I were you I would do exactly what you are doing....Educate, network, and take action...I am not sure if it matters whether you flip or hold to get started....the least friction way to get into the game is typically house hacking if that is an option.
