Mr Ameer is the founder of buyer's agency, Dream Design Property, which helps its clients to buy and renovate properties in suburbs set for growth and then use the equity to purchase new homes.
But he has also worked with many clients who have made costly mistakes when purchasing properties off the plan in a "buy now, pay later" deal.
Mr Ameer said the main reason for wariness about investing in such properties was because of the uncertainties around their value and the risk that buyers may not get what they think they are paying for.
"The concerns are around buying today and the property being completed in a year or two, when it's hard to predict what's going to happen between now and then - there might be fluctuation and the value may drop," Mr Ameer said.
"The bank can never tell you what that property is worth because it's not been built.
"The only time the bank is ever going to value that property is when it's completed."
He said to make up for the lack of bricks and mortar, agents often dealt in hype about the property, which tended to attract first-home buyers and less experienced investors.
"Off-the-plan properties are usually marketed through project marketing firms which have high marketing budgets, so that means seminars, five-star hotels, restaurants, lunches, dinners, flashy brochures, lots of convincing, so you get sucked into the hype of this really good deal," Mr Ameer said.
"But all of that marketing is being paid for by the buyers themselves, they just don't know it: it's built in to the price of the property."
Mr Ameer said other mistakes included overpaying for a property or buying too many properties in suburbs where they were unlikely to be enough tenants to fill the development.
"In a brand-new area where there has never been any other developments, it's hard to say, 'Well, this is what the property is worth', because the developer has got the entire area and that's the price they set," he said.
"Then, after a few years, that's when the market settles and the reality of the prices comes.
"It can also be a risk buying into regional developments.
"There's so many regions with less than 50,000 people where they're speculating growth. I'd rather get in after a few years of optimal results."
However, Mr Ameer does not rule out buying off the plan, saying these properties were an important part of a mixed-property portfolio and could also help buyers enjoy tax depreciation benefits, government incentives and the newness of a property. In the long run you are likely to make money; it's only in the intermediary when you may get hit," he said.
"You just need to be aware of the risks and plan accordingly. Be aware, don't go into it blindly and protect yourself.
"You need to keep a buffer of the potential shortfall.
"If you sign a contract for $500,000, I would say expect the property price to drop about $50,000. You should consider keeping a buffer of $50,000 in a separate account."
