New home buyer

Hi!

First home buyer here, from overseas.. so pretty confused =)

I am looking at buying a 1 bedroom in Sydney, around Wolli Creek. I will initially live in it. I am aware 1 bedroom is not the best investment, however:
- I have been able to save half of what I need and my parents will lend me the other half so I won't have to pay interest to the bank and therefore I plan on paying it back in about 7 years.
- not paying interest means the unit is actually going to cost me less, even if it doesn't go up much in value. Not having a mortgage will also give me more peace of mind (if I lose my job? I won't have to freak out).
- I have considered a 100k loan and getting a 2beds. But if I do this, I will have to rent out the second room to help repay the loan. This means flatmates.. I am 34, I have had flatmates for the past few years and I am totally sick of it now.

So after a lot of thinking I have settled on the idea of a 1 bedroom, worse investment but more peace of mind.

I have found a unit close to Wolli Creek. I know a lot of people don't particularly like this area, but I don't mind. It's close to work and everything I do, still not too far from the beach, and still feels like a good (safe) neighborhood while not being as expensive as Alexandria/CBD/East.

During the 5 months I have been looking, I have seen that prices are lower now. This unit was out for 630 initially and is now down to 600. It ticks almost all the boxes, besides not having a studio space and having another building in front, which I hate. But at the same time, I know that with my budget I won't find one that ticks all the boxes.. storage cage, carspot, noise, balcony, position.

I made a lower offer, hoping that we could settle in between. They know I am paying cash and I am happy for a quick settlement. They said they won't go lower. The unit has been on the market for a couple of months and has been vacant for at least a month. I checked out the last open house and no one went to see it.

I guess what I am trying to understand is:

- should I just accept to pay the 600, even if I have seen that similar units went for 10/20 less over the past couple of months? Another unit like this one in the building sold for 620 at the start of the year. A unit across the road, very similar, sold for 580 a few weeks back.

- is it worth sending another offer still lower than what they are asking, but higher than my initial offer? Or would this be considered rude?

- should I settle for this one, even if I don't love it? My list of musts is: car spot, not on a main street, view, cage, low strata (900ish max), from Mascot to Wolli Creek, balcony, possibly a studio/small second room, newer building, max 620ish k. From what I have seen so far, some units tick most boxes but not all.

Making the decision I am also considering the forecasted drop in interest rates and therefore I imagine that unit prices will go up. So I am thinking that even if I don't love it, the price seems ok for now and I might find myself paying 10/20k or more for something similar in a few months.

Apologies for the very long post, I tried to be quite comprehensive as I know it is hard to give advice. Any advice is more than welcome.

Thank you,
