I have used Sigma 10-20 on an older Nikon D40, it was a fantastic body/lens combination.

Moving it and letting the city tow it will result in the city attempting to notify the owner and holding it for a required period of time prior to auctioning it.  

It is obvious she attempted to clean the lot but it wasn't properly done.

As my body gets older what you can do physically becomes more limited versus you can keep learning with your brain and get better over time.

Have you attempted a first deal, and do you know if it is similar to the states?

Enjoy yourself while you can before your body doesn't allow it.Good luck on both your Financial Planner goal and your Real Estate goals!

With all the legislation coming down the pike on home owners and the fact the owner is 77 years old ( sound mind and body claim entering into contracts) I just wouldn't touch this.Since their is a ton of equity it looks like the lender just wants to foreclose and get rid of the problem.Might be better if she just sells at market pricing and down sizes to another property and keeps her cash as a reserve.If she is on fixed income maybe have some family stay with her and pay rent so she can catch up the mortgage.No legal advice.
