As I started to get deeper into my estimates and as I simulated 10, 20, and 30 years of this growth, the numbers grew to be astronomical..

I ran many simulations to see weather leveraging or debt pay down led to wealth more quickly, and it wasn't even close.

A prudent buyer simulates the worst case scenario happening and buys on that premise.

I am also proficient in crypto, crypto currency, and distributed algorithms.I am also considering making a MMORPG for investing (finding private lenders, lending privately, stock simulator, real estate purchasing simulator, etc...).

Another thing is, in January, when my tenants leave, I'm going to do a little improving on the house and I can probably go from 5520€ to 6720€ (net profit per year) by bumping up the rent 100 €/month.From the credit simulations I've done the mortgage will not cost that much.

Nothing can simulate a lot of rain... gotta throw a raincoat on and observe it in progress. 

I prefer darker colors, but it's a personal preference.I once read somewhere that room colors should simulate nature: dark at the bottom and lighter as you go up (earth, trees, sky).

Google Lighthouse test simulates the loading of a web page using an "average" browser.

Handwritten, cards, simulated handwritten.

You want one that is eye level to simulate standing in the space.You also need software to create the 360 walk-through that can be shared on social media.
