I own a property that I rent to a lovely family, a couple and their primary age son. They both work full time. The wife's father also lives with them, he works full time too.
They've been in the property for 6 years, they have always paid £800pcm, on time, no issues, and I've never raised the rent. Market value now would be at least £1100.
I'm torn between raising the rent slightly to help cover increasing costs associated with the property, or leaving it as it is because I like them.
