I have not has as good of luck with washing machines. 

I suggest putting in at least 4 inches to cap your building and improve energy consumption, At the time of the tear off coordinate renting a blown insulation machine too and you can add insulation from the roof into the attic/crawl space above the ceiling level to avoid interior repairs.

Your real estate agent / Realtor® should be too. 

My last tenants at another property didn't report a washing machine water pipe leak for TWO days.

She didn't get that mindset because that park ran like a well oiled machine on its own.      

As a second generation Realtor® and Investor I am extremely passionate about all aspects involving Real Estate and helping people in my community.

It seems she has never used a clothes washing machine either, as she has numerous questions about that too.  

The ARV's are usually based on retail sales not sales of rental properties.. that's why anyone buying a rental in any mid west rental market no matter what they pay for it basically will not realize phantom paper equity unless your a highly sophisticated marketing machine that can sell out of state

What makes this deal a good one for me, is that you are intending to have it for a long term buy and hold portfolio addition and not a cash flow machine month-to-month; coupled with your diversification of your asset classes and moving some of your asset base out of equities and into physical assets. 

How old are your machines?
