also if she dosnt have at least 3 years worth of account it wont go through even if you put your name to it    if the mortgage broker is dodgy do you really want to be dealing with him
   
and if you do decided to put your name to it  i suggest that you spend a few hours  looking at exactly what your commiting your self to for the next 25 - 30 years   
Its not as simple as signing it and then forgettng about it   and i think its really unfair of family who get shitty when people to dont want to sign there life away

    if you do go down this way  then i would suggest that you tell your sister  that you want a percentage of the houses equity when its sold,  and it will be done in a legal document by a soliciter ect  ( This will probably put her off anyway)   
    This isnt being shitty or being nasty  after all  your potentially signing up to a lifetime commitment of hell and shit     this is called being smart and not getting taking for a ride 
 
       

also  going to add that should  she/ you default at any point and its repossed  then  you  /her are liabable for the shortfall of what is owed /and what its sold for
 
Put simply if you bought it at 200,0ook  but its sold for  130,000  then you will be chased for the remaining 70k for up to 6 years at the very least ,   you wont be able to get a a sweet from a sweet shop,  let alone  credit card  or a loan,  let alone buy another place
and in certain cases it can be up to 12 years that the mortgage companie chases you for,
the only way out not paying is bankruptcy     
its a lot to think about  its not just as simple as putting your name to it and walking away and forgeting about it  its kind of like having a very very expensive  sulky misrable child   

Sorry to hear about your predicament. To me, the deceit is the worst aspect of the job.

Why don't tell your sister you are saving to buy your own property in the next few years?
After all, this may be real possibility for you at some point and signing into this mortgage with your sister is likely to stop you being able to do so.

Look at it this way; Would your sister want you to forget own goals on hold so she can persue hers?

Good luck x

It's looking like a fake sacking is the way forward! I've worked in employment law, so pm me if you would like help with what "L'Oreal" have said etc etc

I really don't think you need to tell her the truth, you just need to say you are really sorry but can't help her out - it sounds like her earnings are quite low to be thinking of a morgage.  in the current market even with your earnings combined she may get refused even with one of those high risk morgage type companies, they dont just throw money at you anymore -and then it's all been for nothing. if she loves you, she will understand why you cant help her... what she's asking is a massive deal and not something she should take lightly. I'd personally never mix family and money issues no matter how well I got on with them or even friends for that matter.  I think it would be really selfish of your sis to just expect you to say yes anyway if shes a mature adult she should totally respect your decision.

You should go and have a look at the risks of getting a joint mortgage with anyone.  Try money saving expert, they have a forum where you can post and get proper advice form the professionals.

You do know that once you even apply for a mortgage together your credit files are tied together.  When you apply for credit the company will see her name come up in association with yours and they will check her file as well.  So if she ever gets into financial trouble in the future it will reflect on YOU.  So you could be turned down for credit even if the buy to let mortgage is up to date but her credit card payments are not.  If she should ever default in a loan/credit card, the company can apply to the court to turn into a secured loan on the property, which ultimately means you could very well end up paying.  Oh and you will be liable for the tax on the buy to let income as well.

Seriously go get some legal advice.  This isn't as straightforward as she makes it sound.

The best thing to do is to stop thinking of her as being your sister and think of her as a  potential business partner, after all that's what the courts would do.
