PC: dilemas on property - I like these....
avoid renting like the plague. only good for landlords. Renting therefore out. So - buy. now let's look at your options again...
sell flat and invest equity : With HA would allow you to get better location (which is always prefereble to size) BUT downsides are limited mortgage options and you have got to get it first... so timing implications
But - on the positive: you don't have to worry about schools for the minute. YOu've got 3 years to play with. So- buy the best location you can afford and start to decide on schools in 2 years (a lot can change in 2 years both to schools and to you).
use equity and hopefully buy at least a 50% share of HA property but struggle and struggle and struggle to pay both mortgage and rent : would the cost of rent/ mortgage combo really be much more than if pure mortgage? What would the difference be? I understood HAs 'cut' was mainly in the appreciation of the capital value?
Downside is restricted mortgage but hey, more capital = better location, even though you would have to share the increase in asset value.
If possible - even if quite a bit more hassle - I'd go down the HA route and get a better location. Unless the difference between rent/mortgage combo is more than 10% above the amount payable if just pure mortgage.
I've always wanted to be the sort of person who has a rich greanny somewhere . My family are the opposite!! They seems to think anyone who lives in London must be loaded and act accordingly
Big choices. Good luck...
