Currently reading 'The Truth About Positive Cash Flow Property' by Margaret Lomas and She is advocating x-coll. Her reasons: The bank can reach further than just the security they hold anyway Maintaining a large portfolio with multiple banks is administratively difficult with multiple loans (Makes sense, but doesn't seem like a huge issue) Tax return are cheaper (Okay) You can have one large LOC with one bank against all your properties (Yeh...) This seems to be the only one that makes sense. She gives an example: If you have 10 properties, all with different banks and all with $20k equity and you needed $50k, it would be difficult with multiple banks. Her point seems to make sense with a positive cash flow strategy that relies on cheapies. You would need lots of growth on a $200k purchase before you could pull equity out? But: If you sell and the bank makes you pay down debt Wouldn't you hit your serviceability wall really quick The book was written in 2007 (8 years ago). Would this have worked at the time of publishing just not now? Apparently she has 35 properties all with the one bank.
