This sounds like a home run and a great first purchase!!

I’ve opened a ticket, so let’s see how that turns out!

The owner also needs to save for big ticket items that may need to be replaced every 10 or 20 years such as AC, hot water heater, furnace, roof.  

I don't think I can ask the seller to evict prior to purchase, although that would be the best scenario.

Have you always invested in owning the parks, or have you purchased some individual mobile homes in parks you haven't owned also? 

I would try to buy properties starting at a specific date so not large ticket items come up.

I purchased a PreREO deal from them about 4-5 months ago. 

A PMC cannot risk a ticket or lawsuit because an owner takes too long to approve an emergency.You do have the right to be frustrated that you weren't informed about the repair as it was being done.Suggest you discuss with your PMC and see what they say. 

Purchase price: $225,000 Cash invested: $56,000 Purchased 4-plex from a wholesaler.

I figure the ones over 50 or 60 years old have already had all the big ticket items replaced.
