If the user is going to be a business use (not residential usage), then you would generally be much better served with a commercial lease agreement rather than a residential tenancy agreement. The RTA lease is set up for home occupancy not for commercial use and so may not suit the purpose you seek.

You also need to consider the CGT implications as well.

How separate from the property do you need to be? A company trustee with you as directors of the company may not provide the separation required. 

Did she not use a solicitor or conveyancer who explained the contract to her?  Oh she sold the unit, was it at a healthy profit?

Also a change of address on your car licence & other bills (insurance, bank accounts/loans etc) will also help.

The contract may provide that the deposit be put in an interest bearing account in joint names of the purchaser & vendor. In this low interest environment, even a $100k deposit will earn very little interest over the 40 days that the funds are held in trust.

As Shahin points out, the RE trust account does not earn interest (this is creamed off by the State Govt for some RE fraud scheme).

Try your luck with council on the premise of needing to replace the fence.

FSR calculations are close to what you've got however you need to understand what the LEP counts in the FSR. Depending upon the definition, FSR may exclude such areas as garages, storerooms, voids, garden etc. The other thing you need to watch is the % or area required as private open space (ie yard area).

As for units with an FSR of 2:1, then 1400 m2 will yield 2800 m2 of development however, same conditions apply (read the LEP). Something else to temper the development will be the required setbacks (front, rear, sides) as well as any height restrictions or building envelopes.

Refer to your building designer/architect/town planner for clarification.

Buckley's chance of success unless you can show that they have breached the agency agreement. They may be incompetent, useless, a waste of oxygen 

Good luck.

Nothing too unreasonable on your part Mosaic. As for weekly opens, depending upon the state you are in, the  agent can only arrange opens in the last X weeks. Are you on holdover/expired lease now? If so, then the agent has to give a greater period of notice to terminate (60/90 days), you only need 21 days.

Inaction/BS answers from the PM that the owners don't want to do work, just doesn't wash – more like agent can't be bothered/too busy/doesn't want to disturb owner/hasn't got balls to ask owner etc.

Generally, I don't change locks/have them rekeyed. In one instance I had a place with 7 different keys: security doors, front/back doors, side door, dead locks etc. Had them all keyed alike.

Next time around, will be looking at electronic combination locks ie swipe card type where they can be reprogrammed for the next tenant. Less than $300/lock.
