Is there a cheaper way to do this or somehow give a smaller deposit such as like 5 thousand pounds?

So what's your solution- Start pounding the pavement for $.

An ounce of prevention is worth a pound of cure. 

Demand for properties in alternative locations may dry up very quickly, leaving you with an unwanted asset that you may find challenging to sell if the market turns sour.Factor in as well that unless you travel often, you will have to rely on trusted local partners such us property managers, lawyers, etc.

I can however predict that there will be more, and they will be priced lower, pound for pound that is.Do note that when I say priced lower, I don't necessarily mean priced more favorably.

Within 4 months I managed to lose about 65 pounds.

I'll let others chime in as to what you 'should' be offering blah blah blah, just know whatever formula you're using now I would forget about it and tell the person who told you that to pound sand LOL!!

Short sale amount could draw alot of unwanted unattention.

If a buyer comes back and tries to renegotiate over things you disclosed up-front, tell them to pound sand because they had an opportunity to build that into their original price.
