We are in the process of buying right now (offer made pre-lockdown and hope to finally exchange and complete in the next month or so). I think it depends on 3 things: is the house the sort of house you wouldn't find in a year or two for the same price? do you plan to live there longterm such that you could cope if the economy tanks for the next few years? is your income secure?
The house we are buying is very unusual. We have very specific requirements related to both the house itself and land and commercial premises all in the same property. We've been looking for years. We found one, viewed it the week it came on the market, made an offer the following week after a 2nd viewing. We didn't think we'd find something that ticked all the boxes again easily.
We also plan to live there longterm at least 15-20 years. So what the economy does in the shortterm isn't really too much of a worry. We plan to add value and it will go up in value with house prices over time. I'm not worried about that.
Our incomes are secure. Actually dh is self employed and hasn't been able to keep up with all the extra clients that have come in during lockdown. My contract will be extended for at least a few more years as well.
Assuming you are in a good position and you aren't looking to turn it around and sell it in the next few years, I can't see why you wouldn't. Particularly if you can get in there and make an offer now post-lockdown. We definitely would have gotten a better deal if we had waited (obviously hindsight is 50-50), but we didn't really know in March what life would look like now. But if I was offering now, I think we could be a bit more cheeky with the offer.
