Luckily even with the extra $100 toward principle the last few years I was able to build up reserves that I'm comfortable with but as soon as money has to come out of reserves I'm sure I will use the extra $100 to replace it until I'm back to my waterline and start putting it toward investments again!

I am preferential to medium/long term rentals so my exit strategy would not be applicable for many years.I make a comfortable living and have a surplus of money saved up but don't want to liquidate my entire savings accounts so I can get just one singular 200K property that may cash flow for a couple hundred bucks over the next few years.Am I missing something or being overly cautious?
