Hi, have name changed as situation quite identifying if you know me so don't want to be outed. I'm pretty dense when it comes to money and don't have anyone who is good with this kind of thing to ask so thought I'd ask here.
We need to borrow 70k for building work that will add 100k + to value of our house (multiple neighbours in exact same house and have had exact same thing done and this has been the case, also in nice area of South East where house prices continue to rise steadily without fail)
I currently have a mortgage of £187500, house worth £250k so 62.5k worth of equity.
DP is not on mortgage as I purchased house before relationship was serious.
We now have DS 6 months and DD 9 (from previous relationship)
I renewed mortgage last year before I found out I was pregnant with DS, have 3.5 years left on a fixed rate (2.79%)
I earnt 45k pre mat leave, am currently still on Mat leave and earning this, will go back to work in January part time and earn 30k.
DP earns 35k salary with 15k bonuses.
I have no other debt at all, empty CCard with only 1.5k limit but don't use it. DP has a car lease which is quite expensive but he needs it for work as drives hundreds of miles weekly, he has no other debt apart from this.
My credit rating excellent, his Good.
So with all this info, what's the best way to borrow the 70k, we need it done by next year as space and bedroom situation are becoming unbearable, so can't save up. We want to pay lumps off early with DPs bonus to reduce interest payments so would like this to be an option.
I have been looking at homeowner loans but I don't have 70k worth of equity, does that matter? Would a smaller equity loan and DP take a personal loan be better? We are getting married in May so will be legally sorted in that sense. Shall I go to my bank and see what they could do for us? (I have been with them for 12+ years) or shall I see a independent financial advisor?
I just want a rough idea as don't want to go in completely clueless!
TIA if you have any advice
