There's another issue or 2 about selling your house then renting, putting the 'excess' in an account waiting to pounce when houses have 'bottomed':
You need to put your cash in an account that earns sensible interest but is very accessible. Good luck!
Generally you get 6 month tenancy, then it becomes short term, month by month. You get precisely 60 days security. Balance THAT against local schools, work, Cubs, friends etc.
One reason there are so many rentals out there are people who've tried to sell but failed but who may well sell for whatever they can get in 6 months time- and not maybe to YOU if you've 'traded up' in your choice of property, thus you'll be out on your ear!
3 monthly inspections by some pimply youth.
The fact you may not be able to rent what you want as your salary only is taken into account thus you, like us, may be sitting on 300K in the bank but that counts for nothing against your salary which will dictate how much you are deemed capable of paying each month!
Appalling colour schemes.
Second class citizenship as a tenant.
So not perhaps when weighed up, quite such a great idea!
