My contractor sealed the holes, unclogged the weep holes, removed dead landscaping that was piled high around the house, and installed a French drain and gutters, all of which we hope will solve the problem.

Missing a few details—namely it seems your expenses seem high.

Look for properties in areas with high demand for rental properties and consider the cost of any necessary repairs and upgrades.Financing Options: Distressed properties can be difficult to finance, so it's important to research your financing options such as hard money lenders.

On the flip side of that rents are pretty high and any homes that are more affordable sell quickly.I have been considering getting into developing but I would have to get partners to help with the financing.

Many people start out that way and would highly encourage someone to go this route if they are able.
