2) I don't ever want to be in a situation where my exposure is that high that I'm over extending myself and squeezing every last dollar out of valuations to have an LVR < 80. My current LVR is more like 60. Others might have a different acceptable level of risk.
3) If a bank started ramping up their rates relative to the RBA, I'd likely look to refinance the whole lot anyway.
4) My situation is a little complicated as I'm using commercial properties as security against a new residential investment property. The interest rate difference between residential and commercial lending is even worse, 100+ basis points. Some banks allow 100% lending against the residential investment property with the commercial property used as a secondary security. To me this seems to be a reasonable trade off to get a residential rate but with some limited cross collateralisation.
After reviewing various options I ended up going with CBA @ 4.6% (1.3% discount)
I highly advise you to stick around this forum for a bit longer and have a look through some threads of people who went down the path you are following now. Some points to consider are:
- You should borrow as much as you can while you can on each property and stick the proceeds away in a safe place. That way when you lose your job, get sick, have long vacancies etc etc you have as much cash as possible to fall back on. The lower risk strategy is the one that puts the largest amount of money in your hands because no-one will lend you anything when you really need it.
- It can be very difficult to refi everything once the SHTF
- On your commercial / resi mix is looks highly likely you have given the bank far more security than they need to have. Give a bank a lot of security and you will get a low rate every time, regardless of whether it's a CIP or RIP. Doesn't make it a good idea though - unless you're the bank!
