The MY BAs has 1 main box, buy older unrenovated houses within 10Km for over $500K returns up to 4% rental yield. Assume you need 9% now to hold, so the out of pocket will be $25K pa before tax(as one can't guarantee one won't lose the job). Simple mathematics shows how many of these one can afford to hold.
I think it comes down to a business decision as to who one's next clients will be. Such decisions need to be made since BAs are businesses and need to survive.
Consider that:
* The number of people who can afford to be $25k out of pocket (1 property) is vastly more than the number who can afford to be $50k out of pocket (2 properties).
* The number of high income earners who have yet to buy an IP is higher than those with one IP wanting to upgrade to two, and especially two IPs wanting to upgrade to three.
* Those who have already bought one or two IPs will be more confident about finding the next one independently than those who have yet to buy a first. So they're less likely to need a BA. Admittedly some organisations do other things eg 'armchair development' that an average person might not do themselves. But for this to work higher returns would have to offset the higher risk and likely higher fees.
It's a numbers game - if you have more clients you make more money. Especially if there are add-ons; more on this later.
To me it looks like a larger number of newbies would be more profitable than fewer more experienced clients (who are more selective about cashflow).
I'll add a caveat in that some BAs have finance or brokerage arms. This is smart business since it gives them an insight into their clients finances and allows them to identify the select few with sufficient cashflow to buy a second property (which should help target marketing). And property management should also offer a reliable income stream if they do this as well.
Fringe religions and spruikers constantly need to suck in newbies to grow the businesses, to replace previous ones have been used up or bled dry. Dare I say it but I suspect that similar recruitment is also required by the breed of BA that specialises in high-priced low-yield 'investment' property, since most of their existing clients will have run out of cashflow to buy more.
Hence to keep the dollars flowing they need to flick the switch to Spruikerville and tell the newbies they'll all be rooned if they don't do something about their retirement income, and of course they happen to have something that'll help. And since there's pain (ie massive negative cashflow), it's got to be doing some good, which it probably is if it would otherwise be flushed down the pokies.
The more sophisticated BAs (eg Yardney & Wakelin) don't spruik directly, but cleverly position themselves so they are regarded as property experts and are frequently quoted in the media (bonus points if you have a regular radio spot targeted at the AB demographic and are treated as royalty by a fawning presenter). And yes they are experts, but it is not always let on that their commentary mostly applies to a select part of the market only, even though the media used is typically metropolitan rather than locally-based.
As I said above, BAs are businesses that fill a role so I don't begrudge them the right to legally offer services and market themselves. Just question everything they say - that's all!
