2.2 Does your sponsor own this property?
his apartment is mortgage, does he own it? Or rented? He hasnt paid full yet+
- Errr..I believe he owns it if he has the papers for it. Others might give the better answer for this.

If the property is on a mortgage in his name, then the answer is 'YES' he owns it ...regardless of how much of the mortgage has been paid off.

.
3.22 If your sponsor has not been employed by the same employer for 6 months prior to the
application does their total income (before tax) from salaried employment received in the
12 months prior to your application meet or exceed the financial requirement you must meet? >>
I do not really get the question. My fiance has been working in BT for 6 years, should I answer no?
- I'm not sure if you can answer Not Applicable with this one.

Not applicable for this question...as you've already stated that he has worked for the same employer for the past 6years.

(Note the word I've highlighted in the question...'IF').
