We are lifetime renters. Sometimes it bugs me that we don't own and are somehow not proper grown ups because of it. But on a day to day basis it is fine and has advantages of being able to move easily and not having to worry about the roof, the boiler etc...
Sinc we moved to this town 9 years ago we have lived in 3 houses - moving into bigger properties as we had DS2 and the kids grew, and most recently to get DS1 into the seecondary school we wanted. We have rented directly through friends of friends and through an agent.
We have always got our deposit back after doing a through clean. We have put up curtains and shelves, with landlords permission (and leaving them) and painted rooms. It is nice to be able to change things a bit but you end up only using cheap stuff since it's not your house so it's a bit studenty!
Moving is definately easier. Just give notice, clean and go. You need some cash to cover two deposits at a time, and may have to pay a bit of overlapping rent, but in the end when you get your deposit back the total cost is not so much. When you are moving from rental to rental you can move out, then go back and do a through clean with nothing in the house to get your deposit back.
One good thing about renting is that the good school premium is not as high as for buying.
I always end up hating our houses before we move out, as they get too small. I don't know if I'd feel the same if we owned and were able to make more changes, but it is certainly nice to be able to move without too much angst.
We rent unfurnished - but that means washing machine, fridge, cooker, dishwasher come with the property, also in our last three houses fitted wardrobes. So if you already own these things you will have to think about what to do with them.
One thing to note is that you can make an offer on the rent, and not just accept the price advertised. Particularly if you make clear you intend to stay for a while. Tennants who move after 6 months are costly and a headache for landlords, so they like to find good longterm tennants and should reflect this in the rent (eg not putting it up each year). On the other hand agencies make more money if tennants move on, so you have to make sure your message about being long term renters gets through to the landlord not just the agent. Also you can find out whether they are long term landlords.
Houses that the landlord has lived in are always nicer (fixtures and
fittings) than pure buy to let properties done up on the cheap.
