Its simple and done every day short of that just show your bank account with the purchase price in cash ready to roll .The banker will give you a pre approval subject to the financials  .. 

This one is the most simple but will cost you the most in the long run.

@Dmitriy FomichenkoIs it a simple process to transfer the money within my market account to a Solo?

If you are trying to be a more informed agent, I think its relatively simple. 

To keep it simple say it’s 50 hours for acquisition then 50 hours per year after that.

Having 8 keeps things simple.

Instead, you pay tax on your profit:  the proceeds of the sale less your cost basis (basically your purchase price (yes most closing costs are deducted, but I'm trying to keep this simple and not try to write a book). 

If you want to sell one-by-one, put one or two on the market as leases expire...simple solution. 

I am using very simple bylaws so I did not feel like I needed to hire an HOA expert to write these up.

Simple thought.
