I worked for those markets as a lender and owner for 20 years and know it by street.I have contacts there if you want to send me a PM I will make a few referrals. if the houses are trashed your not going to get a lot for them if they are rented and stable might get close to the zillow values you posted. 

They would provide private care to 3-4 elderly people similar to a nursing home but on a smaller scale. 

On that regard let me say it 'sounds' like this RV park is in distress with an owner not engaged enough to get the park cleaned up and running clean financially ie non paying residents. 

It's immoral because they took one home, and made it cost a bit more than the ugly home someone else can afford?

That hurts and is hard for an individual small single family owner to compete with.Most of the new apartment construction is ending now and as soon as those get leased up, I expect we'll be in better shape for rent increases maybe into the spring and summer.I'm suggesting to all my rental owners to do everything they can to keep the current tenants happy. 

Your problem is you won’t get owner occupied low down payments on the properties.

They list the owners name.

This is NOT being marketed as subdivided — just something I explored:The city indicated that the lot appears to meet current criteria for potential subdivision (R-1-C zoning, corner lot, frontage & depth meet requirements).No promises made — but it was interesting to learn that a majority of nearby lots don’t qualify, and this one might.Question to the group:For experienced investors/developers — would “existing home w/ potential for income during entitlement phase” be seen as added value?

The buyer had a home inspection done prior to closing.
