Sorry have posted a similar thing before but didn't get many replies. Looking for lots of opinions please. 
Our house is currently up for sale. We have a chance to purchase a house from an acquaintance, a house that I have said in the past I would love to buy. Good size rooms, huge garden and its an absolute bargain being that the person is willing to sell lower than the valuation and it does need updating. It is also next door to close relatives who are getting on in years and may need help (although my help would be limited in that I am not in great health myself) in the future. I am on sickness benefits that could stop if ATOS suddenly find me fit for work (even though I am not) and financially we will be ok with DHs wage in this house if my money does stop. It is further from school than I would prefer but I do drive.
However, the seller is currently trying to find somewhere to buy and is having a lot of difficulty, she has been looking for about 8 months and is just not finding what she wants. She finally found somewhere but its out of their price range and the seller won't drop. Its also not straight forward as her partner has to sell his house so they can buy together and she has just discovered she is blacklisted so has had to go back and see a FA. The money from the sale will not be just hers, it has to be split with her sister so she won't have a massive amount, I don't know about the position of her DP but they have an adequate top budget to go to.
Our situation has changed in that I am about to come into some money and will have enough to make up a good deposit and go for a much better house that doesn't need work and is closer to school (possibly, depending on where we looked). We would need a bigger mortgage though as the money would be used for a dearer house, so if my benefits stop (and we have been living like this for over 10 years and always managed as they haven't been stopped and I have not been found fit for work, although last year I did have to go through an appeal) money would be tighter but we would manage.
Pros of buying the first house:
- Great price, never going to get a house and garden of that size for this price.
- Close to relatives.
- If my benefits stop, financially we can manage easily.
- Money I am coming into can fund doing it up and an extension and paying bit more off the mortgage.
- I previously said I wanted this house but I never actually thought it would happen.
Cons:
- I have no idea how long she is going to take to find a house given that she has already been looking for 8 months!
- Relying on her sale and her partners all happening at the same time and it all coming together nicely (and she won't move into his in the meantime, I have already asked).
- The amount of work to do it up, structurally is good but it smells (elderly incontinent woman lives in a room which would need gutting) and needs completely doing up, although not a great problem as we can make it our own.
- I don't know if her being blacklisted is going to throw up problems.
- Further away from school than I would prefer (its about 2.5 miles away, which I know isn't huge really).
- If my relatives didn't live next door, I am not sure if I would want it quite as much as I do.
- House prices are rising so if later on we do need to look elsewhere, we will get less for our money.
I really don't know what to do. It doesn't help that I am incredibly impatient and I want things done yesterday. I think this is why I am of the mind not to wait, I keep changing my mind. We always planned to move around this time, this house did come up at a good time as she said she was planning on it being Jan/Feb time but this is now not the case and we cannot put a time limit on it.
WWYD in this situation? I keep changing my mind all the time. Doesn't help that I have seen a gorgeous house that I love but as all of my money isn't through, it is currently out of our price range so doesn't really matter.
