Don't sweat it.I'd spend the next 6 months reading posts here on the forums, listening to the biggerpockets podcasts, reading the biggerpockets blogs, and reading a couple of books.While you're add it you should increase your income, decrease your expenses, and start working on fixing your credit score.After 6 months you'll have a good foundation of education and you will start to understand if you still want to get into real estate.

Some investors use a private money mortgage in the second position, and they use that mortgage to decrease their down payment amount.

Once you've analyzed enough properties within your established buy box (make sure you have a buy box), the anxiety will start to decrease, but will never totally go away. 

I have no problem doing this, but it will be the first time in 20 years that I've decreased rent from tenant to tenant. 

Our plan is to buy one property each year all cash until the interest rate decline a little bit.We might have 5-6 properties by then and want to use the equity to buy multiple properties in the same location or maybe large apartment complexes in middle America.My question is: What is the best way to use this equity (since we will not have any mortgages) once the interest rate declines.Our ultimate goal is to have a substantial amount of monthly profit which will allow us to decrease the time we have to dedicate to our w-2 jobs. 

Largest decrease in price in 40 years in Austin has been 2.9%. 

Decreased maintenance and contractor expenses to boost NOI.

Is that profit going to be decreased significantly?

With the upgrade, many commercial property owners see a significant decrease on their utility bills.

This is working out nicely, because the trade off is about equal (i.e. our cash flow increase from paying off the other mortgages offsets the decrease from no longer owning the building).
