First, you are a smart guy and you can figure it out. Most properties are managed poorly, yet remain out of bankruptcy. However, how quickly you learn is what matters most.
The property should come with paperwork for most of the contractors used in the last year. Start with them for emergencies and small repairs. Then “shop” for better/cheaper vendors for bigger projects as you learn the ropes. Ask them their opinion on the major “appliances” as HVAC, plumbing, electrical and roof.
I would also look at the financial stability of your tenants. That’s where your cash flow comes from. If they disappear, you are toast. Review the terms of all of your leases before you acquire the property.
Then do the math. Estimate your revenue and you major cash outlays. Revenue minus expenses equals profit. If there is no profit, don’t do it.
You will make a lot of mistakes. But if you aggressively pursue improvement, you will succeed.
