mrsruffallo every property still has an ongoing maintenance cost, this needs constant resources. It's also not just the costs you may expect, new windows, roofers, boilers etc..etc. Its costs such as housing officers, rent officers, energy advisors, disable adaptions etc. These are all constant costs, some rents are token in relation to the true costs of some properties.
If 30k is not much to live on, then a pen, paper, calculator and a crash course in budgeting is needed!
