I am certainly not suggesting selling is good for all.
In my case, I am no spring chicken and I only started investing 9yrs ago.
I want to grow my assets fast and have a good passive income now.
I really don't want to be 65 before I can have good security and a better standard of living. But thats just in my case at this time.
I did worry about the rent returns as my ips are Ipswich and Murgon.
Murgon is primarily a meatworks town and if it closed, it could affect my ips.
I chose to sell a few to reduce the risk of vacancies. The rent returns there are still very good.
Ipswich is a different matter. With Brisbane rents rocketing up and gov't housing being decreased, I worried about substandard tenants moving to Ipswich. Any tenants coming out of gov't subsidised housing have no tenancy reports on them, so it is likely that many are not going to be good tenants.
It is difficult to get the rents up in Ipswich also. Even after after a new bathroom, kitchen, and internal painting, the best I could get the rent up was $15. I decided to sell a few Ips in Ipswich also.
In regards to CGT, yes, selling will uncur some tax. But it is a 'one off', you don't carry it over year after year, like the interest you have to pay on loans year after year.
My secret is, I put the estimated tax monies into an interest earning account and hold off having my accountant lodging my tax until around Feb the following year. At least that way I get to earn some extra income from the profits before the ato get them in Cgt.
