In these real estate deals you are dealing with 10s of thousands of dollars and when things go wrong on a thin budget is when you see dumpster fires and hear the cautionary tales.Most new investors concentrate solely on the down payment when in reality there's lots of costs: Closing costs, Holding Costs, Utilities Cost, you'll have to lay out money to the contractor for them to start the project, and there's taxes and insurance there's transfer tax title costs.More capital than you think is needed.
