Home loans (Math B*PRIMARY SCHOOL)

Okay so I have a math assignment where in I have to type up some spread sheets for my "friend" ect (The details are in the attached pictures I have comleted akk the spreadsheets but now I have to discuss the assumptions I made during the assignment and I can only seem to find one where as some other kids in my class have found 4000 words worth of assumptions. If somebody could just help me find a couple more assumptions then I could finish this hellish assignment! Thank you for your help smile

hi FiggelHorn

Yes I agree; it's hellish; much sympathy.

In any calculations about which methods are best you are assuming

(i)  the interest rates stay the same throughout the period;

(ii) that inflation and house price fluctuations don't cause a difficulty

(iii) that the repayer keeps earning enough to maintain the payments

(iv)  that they are no hidden costs

Any of that of use to you.  (i) is the main one.

Yes, interest rates change all the time.

And Bob mentioned hidden costs. Banks love to get fees for all kinds of things! There may be upfront costs, transaction fees, insurances. How about taxes, too. Accounting costs ... oh gosh nothing moves without having bites taken out of it!
