Seeking for experienced advice

My daughter is attending one of the schools in BU and currently renting a unit in one of the condos in BU.

My wife and I are looking to buy a property around this area because of the school but I don’t think we can afford any Subsale property because we dont have much cash to pay the downpayment and legal fees. Because of this we are looking for new project since most of the time they will have rebate.

I paid RM1k for the booking fee for D’Erica but most of my friends and colleagues commented that the place is not a good place to raise a family because it will be very high dense. Some say with the price I’m paying D’Erica I can get better units. I booked the 1.2k SQ unit. So now I have lots of doubt on this project.

My questions to all are:

1. How many units in a condo to consider high density? Is D’Erica too dense?

2. Is there any other project within 5km radius from BU that is worth to consider beside D’Erica? Our budget is not more than RM800k.

3. Is D’Erica a good buy? The agent told me there are no much units left or is this one of the tactics of property agent to get sales?

Thanking in advance to all.
