Need help and information

I own rental houses since 2012 with a llc and can show the registration every year 

-show taxes I pay everyear -insurance

I have to put my houses on the market -do reference checks, job verification credit checks -call handyman for my business

Is that good enough

I will have to write a cover letter stating all this information 

I have bank statements in my name for long time with the 500 they ask for

What else would I need to show and provide

Is Jakarta or Taiwan the same as to how easy the process is 

Any help

Would be appreciated
