Credibility is what you can exchange for trust when you have not earned their trust yet.Notice that I on purpose am not giving anyone a set of instructions on how to be credible?

That said, you could use some of the on-line calculators to provide a rough idea on a property, suitable for triage purposes.  

I write the property address and quick description of purpose on the receipt.

Buying a property without funds or funding and the sole purpose of making money on the transaction is practicing real estate without a license! 

So it’s exactly the same as if you were paying 100% in cash because the equity in your property is basically cash.If you have equity in a property in your home country that you are never going to use for any other purpose than buying a property in Mexico, by all means, take advantage of the HELOC’s low interest rate and use it to buy your Mexican property.

I think they serve some good purposes, but if you're sourcing capital for a certain type of deal you'll probably be better-served procuring capital once the deal is tied up ideally.

Their real purpose is to deter tenants from frivolous law suits against you.

Oh my, very good tips, but as to recording phone calls and taking them to court, better check applicable laws as to notice of recordings, unless you have 3 or more on a conversation, privacy is assumed.I've used recordings and gave notice that is not so obvious but meets the legal requirement, by saying such things as;"You know George, I'm not discussing this issue with you privately at this time"....Or "You know that under the circumstances anything you tell me is public knowledge as I may have to repeat any part of this"I doubt a landlord can justify saying it's recorded for training purposes LOL.Otherwise, not only will your recording be tossed out, you may get nailed for wiretapping!

The financially intelligence know that by giving each dollar a purpose you are creating wealth.  

Taxing entities want max revenue, so they try to have a realistic assessment of value for tax purposes.
