Personally I hate OTP and I'll tell you some reasons why, then you can make up your own mind.
A big problem with OTP is, you see many people that sell them a few years later the sale price is less than they paid, or still the same as they paid - why: because the price was too high.
Often they have the capital gain priced into them, but that capital gain is not guaranteed.
OTP is not a beginner's strategy, it's for later when you're more experienced and can sniff out the bad deals. There's several reasons for this.
OTP the contract is written in favour of the developer, as opposed to a standard real estate institute contract for buying established.
OTP usually pays more commission and more marketing, so you're wasting more of your purchase price.
OTP you are signing up now for something you do not have unconditional finance approval for. No bank will give you an approval that lasts 2 years, in 2 years circumstances change:
-Valuation could go down
-Bank could place LVR restrictions on the area due to lots of developments
-Your income/salary could go down or your job change
-Family circumstances
You can't really buy other property while it's being constructed without risking your finance approval, without being very careful in the meantime. Whereas with established property you would buy one at a time until you can't buy anymore. With OTP you have to always be conscious of that settlement coming up and it really ties you down.
Some questions to ask:
-What is the median price in the area for units like this, are you buying ABOVE median price, if so it's possible you are paying too much, consider negotiating down or walking away. You will have trouble getting equity out because valuers are often reluctant to value above median unless for a very good reason.
-Are you paying a premium on top of what established units can be purchased for, not what they are advertised for. For example if an established unit is $500k, you might be able to buy it for $475k. How much extra are you paying on top of this? Don't pay a premium due to it being new, in a couple of years it will be just like the others and prices will normalise.
-Ask yourself why you don't buy an established property. Try and buy one from a motivated seller, that you can really negotiate the price down low, $20k-$50k below median price or more. Then in 6-12 months you can re-value it at the new median price and take equity out to help buy the next property.
Alot of the above is because OTP does not match my growth strategy, but it's just my opinion and thought I'd share it in case you can identify with any of those points.
Some OTP can be good, but it's not an easy game.
