How wide are the lots? I have a high density older park with the lots about 31-32’ wide with a single parking space off-street.
Also, I think with the tighter parks, it really depends on the demand in the Market. With my park, its being marketed towards those who want to downsize (Biggest homes are 2 Bedroom), retired, just starting out, divorced, etc. There are a good number of people who want some yard space but not big lots to maintain (they have other things to do). Just because the lots are tighter doesn’t make the community less safe or attractive but it does limit your target market. That’s just my two cents.
