However, I usually go the conservative route when comping deals (NOT based on speculation or exaggerated predictions).

Any long term predictions (10+ years)?

@Carlos PtriawanThe best part of being an investor is that investors get to make decisions where they place their capital AND then benefit or suffer from the consequences of those decisions.I can say NO ONE has ever become wealthy investing in CDs.I can say MANY folks have become wealthy investing in real estate.I can’t predict what the future will hold but the long term trend (unequivocally) is the price of real estate both sale and rent increases over time.I’ll keep my capital in real estate not CDs.

There is no spreadsheet that will predict a perfect investment. 

The Fed recently adjusted its short term projection to one quarter point rate drop for 2024, though it had earlier predicted as many as three drops.

While a single stall garage might be only a ~10k adjustment on an appraisal depending on your local market, the lack of garage can kill market value which is harder to predict.
