Lately, the topic titles on the BPRE podcast have sounded more like On the Market show, and the last On the Market show sounded more like a BPRE episode.

Quote from @Nadeem Alamgir: Hey Brandon, those hiccups sound pretty normal, especially with an older property.

Quote from @Ian Hutton: Quote from @Jay Hurst: Quote from @Ian Hutton: Hey everyone thanks for the feedback, I did forget to mention I plan on buying more properties (which is why I’d like to reduce my debt) let me know if that changes any answers, but sounds like paying off the 88k 6.4% interest is the way to go  If you plan on buying new properties do not pay off any debt.

I would assume that there are sound proofing updates that you would be able to do such as windows, walls, etc.

It sounds like you have a good start already.

Sounds kind of like buyer's remorse as much as the actual noise.
