Today I get a call about water in the utility room of one of my houses .

If you don't disclose it, technically its loan fraud and you can get in hot water. 

I replaced the HVAC in 2012, water heater in 2010.

Talk with local investors and property managers to get sense of vacancy rates for your area/asset class.What about water/sewer and lawn care?

I found 3 last week off of matching water shut off notices against inventory not receiving mail... it's just you have to DIG with pain points) Today you have to be able to model everything around what the different cities are doing for housing plans......

I found it on MLS, negotiated a decent price, then renegotiated after the inspection found a significant water leak and related damage.

I did not realized that the HOA does not cover the water bill (which is what I was used to).

Same as you can't convert a coin operated to a regular type without major work (yes, I looked into converting some extra units I have).For washers, go with top loading units, they are more reliable.Consumer Front loaders are cool, eco friendly, use less water, and electricity, and more expensive, but, they break down more.

Mine includes but not limited to, roof 25 life span, floors 10 year life span, appliances and hot water heater 12 years, hvac 20 year life span, bath and kitchen remodel 15-20 year life span.

@Zachary Bellinghausen - From a quick look, you need to add water/sewer and lawn maintenance to your expenses.
