Petrol at €20 a day equals about €450 a month (work days only), which obviously accounts for a good portion of the €700 budget discrepency. That leaves €250pm
Should we try save now or get rid of Loans first?
Absolutely get rid of loans first before starting any form of saving (bar, perhaps pension). (See comments below)
I also thought about changing the car as the millage is high and a diesel would be cheaper to run. i still cant believe €700....
If I were you i'd try to convert car without increasing borrowing - a smaller diesel car with value roughly = to your petrol car might be a good idea. Is there any way to reduce spending on petrol? Is rent nearer your workplace significantly more expensive? Or even better, can you car pool???
Aside from a general improvement in your finances, you've said your medium term goal is to buy a home.
Now, i'm not going to comment on the risks or suitability of doing so - im just going to lay out the practicalities below for you to think about....
Price
Im guessing to buy a property similar to the one you are renting in would cost in the region of €200k - €250k. Lets say €225k for arguments sake. You'd probably need a good €25k deposit to convince most banks to lend to you. (On a side note, at your income level, the banks would lend you up to around €240k if debts were cleared)
Repayments
This balance of €200k would have repayments of €934pm for a 35yr 4.49% mortgage. A shorter term, or higher interest rate could push this up to €1,100+.
How to Get there!
If you reduced spending by €75pw, your partner or you was able to bring in an extra €100pw (gross), and you ridgely saved the €250pm unaccounted for above, you could probably accumulate €10k savings a year. At that rate, you could clear ALL debts within 1.5yrs. After clearing the debts, you'd have €570pm extra (no repayments) to play with. Saving as before and adding in this €570pm extra, you could probably save €25k within another 1.5yrs.
Timeframe
Now - 1.5yr time: Reduce spending, Increase Income, Budget - clear all debts
1.5yrs - 3yrs time: Save €25k deposit
3yrs time: Earliest date you could comfortably purchase home
General Points
> Obviously a new baby may increase costs and hence increase lenght taken to save/reduce debts
> Starting a pension is highly advisable, but may reduce ability to save/reduce debts slightly
> If you can cut costs/increase earnings by more than i've outlined, you will get to your goal/dream sooner
> I have not allowed for interest relief on the mortgage. Broadly speaking, with a €25k deposit saved and all debts cleared you could comfortably met the anticipated mortgage repayments
> You have a good salary in what is still a relatively safe profession. If you can get a handle on your finances as outlined, you will be in a very good position. I strongly believe increasing your income by either you or your wife doing a small bit of side work (grinds, lessons, p/t work) could absolutely transform your finances.
Best of luck!
PS: Don't let your desperation to buy a home cause you to do anything irrational or foolish! Solid saving and work will get you there soon enough!
