I have been known to buy extra on those sales. 

In other words earning income from the fast turn over and then holding for the long-term income.I'm looking to build my buyers list.Ed Mack

It does look like some data mining based on key words, a link here, county records there...Always trying to sell you something extra... 

Then I asked, how much are you putting out extra per month?

But fixing things quickly maybe keeps the tenants for an extra lease, which is worth it as well.

My question is, will it be a better decision to put 20% down on the property I purchase in order to avoid PMI; or to put 5% down and use the extra cash to potentially line my self up for another acquisition in the near future?

She does earn 3x the rental amount. 

You have helped me realize that I probably won't be a "good candidate" (haha) for banks right now as I am earning $0 as a full time college student.

But, if there is a possibility of a short fall....HOA/other debts that can't be negotiated out with the bank ( the lender will only contribute a set %) you need to be prepared to pony up some extra money above and beyond the purchase price. 

Learn as you earn.
