The entry level homes I have been providing refrigerator and washer/dryer but tenants are responsible for repairs...and last two tenants brought their own washer/dryer.

Even the price of a refrigerator will vary from region to region.

The mortgage payment is about $990/month and we have listed the house on the market for $1350/month(washer, dryer, & refrigerator included).

They have made a few comments regarding there being no refrigerator or washer/drawer.

Counter tops not as easily.Life expectancy of a counter top is more than that of a refrigerator.Some tenants prefer to use their own refrigerator.

The key is to see what your specific house competition is offering any why.For example, in California a lot of houses do not offer Refrigerators.

You'll only be responsible for what's inside the actual unit itself, so maybe replacing a refrigerator or stove once in a blue moon or what have you.  

Not only was the oven covered in a thick layer of grease, the countertops were THICK with it, the window in the kitchen was covered, the microwave, refrigerator, sink, cabinets, floor, EVERYTHING!!

I actually asked my property manager if I could stop providing refrigerators and stoves, but she said it is expected in our area.Mike
