After Toledo got about 5 inches of rain in a short period of time, my duplex started to have water come up from the drain in the basement floor, and out of the sewer drain in the basement.

Live on your parent's couch or in a van while you pump all that money into properties. 6.

The insurance -"rental dwelling policy" does NOT cover basement flooding due to sump pump malfunction or sewer backup.

The water well costs isn’t as bad as I had thought.

However, Canon's 10-18mm zoom lens blows that out of the water, 16.2 mm to the same maximum as the stock lens.Just as a discussion of megapixels is worthless here, a discussion of aperture and the Ricoh prime lens's clear superiority is almost as worthless -- no one shoots real estate without a tripod, and listing shots aren't exactly packed full of stunning examples of bokeh effects.So let's just tell the OP the truth -- there is no such thing as competent point-and-shoot outta-my-back-pocket DIY real estate photography.

Then any rehab you have those cost, they add up quick from light bulbs and batteries to water heaters and air conditioners.Once you get a tenant in it they will find things that don't work that you missed because nobody has been living there get ready for a few calls to sort things out if its been awhile since anyone lived there. 

I'm mostly worried about the interest rate changing on the HELOC and not being about to afford it and go under water.

I don’t have anything going toward cap x or anything like that right now, but all the major things have been done within the last 10 years, with the furnace, water heater, and roof done within the last 3 years.

Require fire extinguishers in the kitchen, laundry room,  water heater room.
