And gradually the house value was creeping back up toward what I had paid.

The value has recently gone back up to what I had purchased it for.

What if in 30 years when you want to retire the market is down and you can't sell and you held on to this property for so long and have to wait another 5 or 10 years for it to pick back up?

The remaining amount of money that I have; that my friend gives me is going to be back up money.

You can absolutely work full time and manage your properties but with this being new it’s always nice to have a backup plan just in case your situation changes and you don’t have as much free time as originally planned.

Or as @Ashish Acharya, back up all the way and have your QI purchase the new property and hold it for you in a reverse exchange until your old property sells.There's ways to mitigate but the timing is serious and there's no give.

It goes up, peaks, goes down, bottoms and then goes back up again.HOWEVER, while it is a business cycle, most people only think of it as simply a cycle that moves against a horizontal line.

Pretty much have it stripped down and now we will build it back up. 

I usually burn through them at 2x speed, but I'll back up and slow them down for something that sounds particularly enlightening.
