@Jack Martin Thanks for your advice! The first improvements we will do to park #1 is cool seal the roofs. I will also check the condition of the entry way (sign, mailboxes, etc.). We also are hiring yard people instead of having residents mow their own grass, which is done with varying degrees of diligence. LOL. Hopefully if they see we care about the outside then they'll trust us to let us make repairs on their home. Park #2 needs to up the price for our 1031 exchange so the owner will put on new back porches, cool seal roofs and do other improvements.
My mother was so hurt by their living conditions and asked why we would want to buy it. She was almost shell-shocked. I told her in the spirit of @Frank Rolfe "Don't be put off by the beach towel (in one case it was a Confederate Flag in Park #2) as the curtain" and told her it's by God's grace she doesn't have to live there. One place in Park #1 had hefty bags over the windows and my brother said it's their blackout curtains. I saw one in an adjacent park to Park #1 that had a washer, dryer and fridge in operation on the front porch! LOL! This process has been adventure, to say the least, and I am loving every minute of it!
On another note, we just bought a second home in Peoria, where will relocate next year! I love some Arizona! First time I visited, we bought a house!
