Moving home mortgage advice please

gardenbug

Hi, new to this forum so please be kind.
House is up for sale for 3 months, not found one to move to yet. Spoke with mortgage lender before marketing house to get an idea of what they would offer me as i need to borrow more (approx 25K).
Have 26 years left on current mortgage (approx 70K) (am out of the fixed period) so rate is 0.5 above base rate for remainder of mortgage. I am able to port mortgage (i theory - i know lender will not always but it states in my paperwork is possible). With such a good rate would like to port it and borrow additional on separate mortgage (looking at 5yr fixed 2.89%) which i would overpay on to clear this first and then still be left with lower rate on main mortgage until it ends.
Does this sound realistic or am i best opting for new mortgage for whole amount of 95K but obviously would not get such a low rate now?
So much to think about my brain is now hurting
Thoughts appreciated

Your best option depends on the term of your current deal and your future plans.


Also, you need to consider how you would handle a £95,000 mortgage if base rate start to rise.


If unsure, engaging a broker is the best way to ensure you get the specific advice you need.


(Your broker will port the current mortgage for you if appropriate)
