I have just received an interesting piece of information from the Malaysia My Second Home Centre in KL.
Aside from restating a lot of information that will be familiar to readers here, there was one paragraph that caught my eye, viz.
However, at the initial application stage, applicants must show proof of liquid asset worth RM 350,000 (minimum) and monthly income of RM 10,000 if they are actively working compare to retirees who may comply to the requirement of RM 350,000 in liquid asset without show proof of monthly income.
The above paragraph points to a subtle distinction, at the initial application stage, between those applicants who are still working and those who have already retired. In the latter case, the suggestion is that no proof of monthly income is required.
I hope that this information is both accurate and useful, although sadly it will not change my decision to abandon the idea of retiring to Malaysia, recently confirmed during another visit to Penang. 
It would be interesting to see the reference to the above quote as it does not concur with the current information on the Malaysia My 2nd Home website.
However, I hope it is true for future applicants as the RM10,000 for some retirees to show, including myself, was a hurdle.
Most retirees utilize financial plans to minimize taxable income, therefore, evidence of
income can be difficult to produce.
I agree with papaya except to add that, on acceptance, retirees over 50 who can show RM10,000 per month from
recognised Government Pensions , do not need to deposit RM350,000. Correction RM150,000.!
edit: sorry typo.... Scott has the correct figure...I should know...I have it on deposit and 350,000 would be a lot.
