I am interested in understanding the mechanics behind this. Are you able to elaborate?
When growing early, you need a couple things:
1) Easy access to cash outs
(flexibility)- personally I don't think NAB are that great in this space compared to the other majors. They have a stricter policy in the LMI range, which is generally part of the aggressive accumulation phase.
2) Lender order: ideally you pick the more conservative lenders that treat OFI debt harsher first, and then move to lenders that treat OFI debt at actual repayments later. Overall, this should increase your borrowing. Noting that, as mentioned earlier today, it's not like NAB are the only lender that take actual repayments - so this can be manoeuvred around.
3) Serviceability: you also want to make sure that you have the borrowing power to release the funds. One way to check this is to map out a pathway for the next 12-24 months (2-3+ properties potentially) and see whether equity release is still possible.
Adding one more to the mix that I like; valuation models. This is probably more timely, but given that modelled estimate vals tend to come out stronger, this can really help accelerate the investment journey. Going to a lender that lets you use this can be a 'bonus' that gets you where you want to go quicker.
Eventually as the portfolio matures (5+ properties) beyond a certain point and you've got equity held up in lower serviceability lenders, its likely there'll need to be some refinancing out to higher serviceability lenders. That's why most people with 15-20+ properties hold their debt with Macquarie, NAB, etc. Releasing equity when you get to this stage with low serviceability lenders is next to impossible, so there's refinances out to these lenders.
This is all part of an effective finance strategy. Perhaps worth noting that price is generally down the list in terms of priorities.
