But we also knew that I wouldn't be not making money forever and we wanted investments that had the chance to appreciate and really let us grow our wealth so that we don't have to be stressed about things like "how are we going to put kids through college"

Heating and air systems don't last forever.

Multiples of any CF (although won't increase at this rate forever..)

I use granite for counters because it's almost as cheap as linoleum and it lasts forever, I have been doing tile and 50 year laminate floors everywhere but the bedrooms, they get carpet.

So I do intend to hold each rental forever, unless appreciation accelerates to the point where selling becomes a no-brainer.

Many investors that buy rentals think when they buy them its like a marriage its forever.. then something happens either they get burned out landlord syndrome.. or other personal issues and a sale is needed.. they are on their own.. the Turn key company cannot afford to sell the properties at RE commish rates they would go broke plus a lot of them are not licensed to do so and its not their business..

Needless to say, the rehab took forever @ $15k at a time on a $250k project.

Far from ideal to be sure, but that won't last forever.

Ultimately, we're going to have to hope that either someone in government takes the reigns and cuts the spending or that the IMF is right about the fact that we can grow our debt forever. 

These are all expenses that are forever but people just accept them because that’s what it’s like in their market.
