I know at the moment you want to move into a bigger home and have a second child. You dh is older and you said you can only get a mortgage for 17 years because of his age. I presume he could be 52/53. You feel if you don't get a bigger home now you will miss out and you won't have the space for a 2nd child.
- Does your dh really want a 2nd child considering their age and the fact they could be retired before the child finishes secondary school? How will you afford to put your current child and this child through college?
2 Your mortgage is currently £750 pm. To move to a new house this could change to £1400pm or £1150/1200 pm if you buy a fixer upper? Interest rates are going up so what happens if rates go to 6 or 7%?
3 fixer upper house are out their but the cost of building materials, paint ect have risen a lot and it hard to get good trades people to do things and they are not cheap either. Then you start to work on a house like this find problems and end up with a lot of unexpected expense.
4 When you apply for a mortgage banks will stress test you to see if you can afford to replay.
Also they will look at car loans, credit card ect. They also take into consideration how many kids you have. If you have another child you can't borrow as much.
5 Another child means that you have to live on maternity pay so you less income coming in for X period of time. You have the cost of nursery fees and the hassle of finding a place.
As your current child get older the expenses will get higher. Your extending the length of time you will children dependant on you and doubling the costs of bringing up just one child
As children get older they get more expensive.
6 At the moment the cost of living has gone crazy. Electric, gas, petrol have all shot up and are due to rise even further. Foods bills will be rising further as well because the cost of fertilizer has doubled and farmers cost of diesel ect will have to be passed on.
7 What happens if you have a 2nd child and you or your dh can no longer work because this child needs care?
Even one of the posters here said she is good with money and budgeting but she can't budget at the moment with the way everything is rising. Another person here did what your planning on around your income and she is finding it hard to manage on their income.
It not just that prices are rising but people's wages are not going up at the same rate and taxes are rising also.
I think that you would be better off staying in your current home and not having a 2nd child.
If you move house, take on a bigger mortgage and have another child I think that your just going to make life more difficult for you all. It important to have some spare cash to put aside into savings and a pension as you get older. You also important in case anything unforeseen happens that you have some bit of a buffer.
