My best friend's marriage broke up, leaving her with a vast house and mortgage and business loans. My own broke up shortly afterwards so I moved in with her, in effect I was her lodger, but didn't pay rent because what I did was help her to convert her house into flats and re-decorate all the rooms, and we let them out. It was only about two weeks before we got our first lodger, and I really enjoyed my time there. Most of us had broken marriages, of both sexes, and it was a wonderful halfway house while we needed time to sort out our heads and decide what we wanted to do. She still has lodgers over twenty years later, but is down to two rather than nine or ten at a time.
Because of that experience, whenever I have had a friend in financial difficulties I always suggest having a lodger. In all the time my friend has had lodgers, she has only ever had two difficult people. One was a 21 year old female thief with an eye for toiletries, the other a 50 year old gardening alcoholic - she took him on in the hope he would keep the grass cut for her but he was drunk in charge of the ride on mower and mowed all her borders!
One of my friends now takes in foreign students, so that she gets a bit of a break from them at certain times of the year. Another took in a gardener and they are now in a relationship. Another took in a hairdresser and gets her hair done for free!
I was thinking about it the other night, and mentally planning how I would sort the house should anything happen to dbh - as one does on occasion.
Firstly, you get their rent, and secondly, you have someone to keep an eye out for you. As you do for them. And with a bit of luck, you even really like each other. My friend now has an annual reunion for all her previous lodgers. Sometimes it was like having a party most nights - but of course you could always go to your own room if you didn't want to join in. Our children absolutely loved it. I could sort of see the attraction of living in a commune as a result. I even tried to get DBH to move in when I met him, but he liked a quieter life.
