Hi StaticSplit,
Without knowing more of your financial details, and your status within the UK long term, it's going to be more difficult to buy in the current and certainly forseeable future in terms of the economy. I'll assume your husband is working full time and is British.
The availability of easy to get mortgages is long over. Nowadays, pretty much all lenders will require a 25% deposit, so you'd be looking to put down around £22500 on a 90K flat/house . Add in the associated fees for solicitors, agent fees, surveys etc and budget 1-3K on top of that. 5K simply won't be enough. There is 'talk' of economic betterment at the moment, which is good, however there are also murmurings of a second 'fall' thats imminent as well - if that is what happens, no one knows. So if things do get better, no 2nd fall, then more mortgages over the coming years should be launched back into the marketplace. 100% mortgages will take more time to appear again, and prbably when they do, will be very much more stringently assessed. I'd think it'd be the same for 5% and maybe even 10% downpayment mortgages too.
I definitley suggest looking out and searching for independant mortgage brokers who might have products avaialbe which better suit you and your needs and situation. There should be some in your area/town or city and they'll look futher into what is around, and your situation more closely.
Fixed rate mortgages are available, and tied to the above, depending on how much you can put down will determine what kind of fixed rate deal you'll get and for how long.
Lastly, you're question on is it better to buy now or pay rent for now and buy later.. this is the 64 million pound question ! the answer to which is 'if you can afford to buy now, then do so' - that statement blanket covers everything to do with your life, your partner, your lifestyles, your finances and your ambitions! and leading to it, only you will know the answers to begin to evaluate everything concerned!
There are more aspects to all of this, just the above is a high level response to you.
