Condition of house?

A condition of the sales of the units will be to keep the units in the park for a minimum of 5 years, and no subletting will be allowed.The park has been approved by the City to allow for five additional spaces to be installed in the North East corner of the property.

If the lease is renewed who is responsible for removal of tower and restoring roof to original condition

It allows you to buy properties for less, because of their condition, improve their value, attract better tenants and create equity in the process.

Because of the area, condition, and current market, I can exit in multiple ways (wholesale, flip, rent) with some cash in hand. 

Quick background on the property about 130k is owed on the property and in the condition it's in it may sell for about 180.

Let's say the tenants have lived there for years and always paid on time and kept the place in good condition.

I am not a wholesaler but I do deal with them as an investor and what I can say about the advantage to a seller is the speed of close because a good wholesaler will have an inventory of investors that can make decisions quickly and close deals fast (e.g. cash close in 10 days or less in as is condition), when a seller is in distress and needs to get out of the property for whatever reason.

And for sure it depends on market and market conditions.. some markets you can drive down each block and see three board ups in other markets you will be lucky to see one distressed house out 500 homes.. 

Main key point is prevent conducive conditions allowing or encouraging termites to invade your property.
