@Rodney Lorenzo Compared to the other buildings in your area how does yours look? How it looks outside how it looks inside? How is the flooring or the paint job?
Maybe if you install new vinyl plank floors with a nice paint job and some new door knobs you can make your units look much better and attract a bit better tenants? This should not cost much.
If you want you can DM some pics and I might be able to suggest some low costs fixes that can improve the look?
For the future, I have a rule for myself, I will never buy a property that I do not see myself living in it. If I do not feel safe in the area I will not get close.
To attract better tenants maybe offer 1 month free in the first year, Maybe lower rents just to get a bit better tenants?
Usually higher cashflow properties means there is more risk in them that's why the cashflow is better.
You usually want lower cashflow properties but with better appreciation in the long run.
Ultimately, consider this experience as a valuable learning opportunity.
You now have a better understanding of where to focus your search and
what to avoid. Think of any losses as a form of tuition in the school of
real estate investment, which will undoubtedly serve you well in future
endeavors.
