Depending on your interest rates you may be able to get a better return on your excess money than by paying off the mortgages.

Speaking as both an investor and realtor based in FtL, these small MF are very difficult to get into at the moment due to excessively high pricing leading to negative cashflow if you plan to finance them. 

After looking at it, it’s not really leaking or dripping, more so just a little moisture around the seal.

Heat and moisture gets trapped under the house and the heat wants to rise but the LVP creates a vaporlock, thus inhibiting the mold growth. 

As a Property Manager in a market where many owners choose to manage on their own, I've seen several examples of owners losing their homes or properties because their tenants did not pay or caused excess damage.

My GC primed and painted over them a few times thinking they were just old, stubborn stains that needed extra product, but they kept coming back after each rainfall.I hired a water intrusion detection company to help me pinpoint the problem - they said the new roof seemed solid and that based on infrared and temperature readings, the moisture is coming in from the partition walls.

While that bodes well for opportunities, the out of pocket cost would be excessively high as well.

When you buy a property, and hold a mortgage on that purchase, the excess cash you have between rents and costs is a form of profit but the short fall is NOT a loss, it's additional capital investment. 

This works reasonably well for many situations, but it can lead to issues when you happen to have a particularly wasteful tenant that uses excessive amounts of water and/or electricity.

Both me and my husband are currently working, so the excess, if we do have it, sometimes goes to one of our rental houses.
