Yes 1k sqft is small but probably much better than living with family.

Now, three years later, my tenant reported cracks in every room—paint cracking and full-line cracks in the bathroom, living room, and bedroom (walls, ceiling).A drywall contractor looked at it and said it’s normal wear and tear, but I’m concerned since it’s in every room.

They live in a semi HCOL area called Torrance (house is in a good zip code 90503).

Consider using an FHA loan to secure a 1–4 unit property with just 3.5% down and take advantage of tax benefits by living there for at least two years.

My most trusted and often used contractor who lives in the area, and is practically a friend is the emergency contact.   

The kitchen, living room, and bedroom are one room, the laundry and bathroom are together.

Quote from @Roxanne Whitaker: Please be aware if you buy an investment property and do not live in MD, when you go to sell it you will pay an 8% tax at settlement. 

There just trying to eek out a living too.

They're investing tons of money into those areas, and attracting a lot of good renters who work in the medical profession and will pay good rents to live close to their jobs. 

There has been a squatter living in it for about 3 years, that refuses access to anyone that I have sent out there to assess the property.Safeguard personnel stopped communication with me last year.
