I can certainly be done, but be sure you're going slow and taking time to make sure all the i's are dotted and the t's are crossed.Of course... this is pretty much why title companies exist - to mitigate all the issues and complications of self-closing, but I understand that some properties are so cheap that the added cost of a title company isn't always economical.

If you do slow, incremental increases, they will eventually reach the breaking point and have to leave, or you will have to stop raising the rent to keep them.

Add the potential for accelerated inflation (my calculation 30% this year) you should be fine.  

I currently have 42k in cash with another 50k tied up in lendingclub slowing being payed out to me.

The only thing that is slowing me down a bit is being tied down to a very good paying job and having a wife and two children.

@Erika Calderon slow your roll. 

Refunds for no stated reason, slow pay etc etc.Not sure if they will ever get there.

Challenges mostly revolved around having to lease out a different unit unexpectedly during a slow rental market in MN winter, and dealing with an onslaught of maintenance issues at my other properties.

@Raden Mantuano,The market is still hot, but is slowly slowing down for sure with the higher rates and with prices continue to slowly rise.

As long as you are considering growth - even slow, steady growth - there are great benefits to keeping a mortgage.
