Mumsnet gives LL's such a hard time, so i'm going to start this thread and then hide. I started investing in my early twenties (myself and DP bought our first home, then we let it out and bought another cheap one to live in, remortgaged our first and bought another let, did it up, remortgaged it and bought another etc etc). These were in the days of self certs, you wouldn't be able to do it now - it was so lax, and property so much cheaper (our first one was a 3 bed in East London for about 127k). We took money out on credit cards for deposits! Anyway, we now have about 40 odd. We are genuinely decent landlords - we rent out at market rent, but go above and beyond making our properties lovely - we refurb a few each year and put in dishwashers, wine fridges - i make them how i would want them. It helps that i love interior design and i care about the local environment - i would hate one of our properties to be known as one that brings down the street.
Our tenants are mainly students and they are mainly student flats - ie a family wouldn't want them.
We both come from lower working class and neither had any financial leg ups, although my parents couldn't have been more supportive in the early days - helping us paint, clean, put in kitchens etc.
It's been bloody hard graft over the years - many lovely summers in our twenties stripping wallpaper, but its paid off and we are now comfortably off with lots of hilarious memories. We are still shit at DIY.
So AMA!
