Ooops, didn't do the legal thing with the tenant's deposit (it's sitting in my savings account), but hey this law is very new and MNet is anonymous.
In terms of pre-interview, what you ask depends on what you're looking for from tenants. We knew we wanted a non-smoking couple, responsible enough to sort out any problems with flat and neighbours if we weren't around, who didn't have a too long a commute to work (so they wouldn't up sticks after 6 months and move to somewhere with an easier commute), and could afford the rent.
So, I asked about where they worked, why they wanted to move and from a few questions I tried to get a sense of what they were like - instinct tells you a lot. I always bore in mind that I would have to be able to communicate with the tenants effectively, so if I found them difficult to speak to, I gave them a thumbs down.
As I was so overwhelmed with responses, I outlined all the negative aspects of the flat and if they were still interested and I had a good feeling about them, I'd invite them for a viewing.
For references I always seek proof of ID (eg photocopy of passport checked against original), proof of current address, proof of employment, landlord's reference.
Downloaded a standard 6 month assured shorthold tenancy agreement from internet and amended as I pleased.
I just made up a basic inventory of my own, listing furniture and condition, then making space for your signature and tenants signature and date at bottom or list.
Might sound like a lot of hassle but once you have all these documents saved on your computer, it's just a case of adjusting names and dates for new tenants and the rest is easy peasy.
One thing I make sure I always do is the gas safety check every year. I'd hate my tenants to die soundly in their sleep of carbon monoxide poisoning.
The other thing I do, which tenants really like is a "Welcome Pack" giving info as to who supplies the utilities for property, all my contact details if they need to contact me, where the nearest GP is, what day the bins are emptied, who the neighbours are, how the boiler, fridge, freezer, cooker works, etc. - All my tenants seem to love this!
hth and good luck with it all!!
