When you get flooring there's people sitting at the computers in that specific area, so that's usually where you make large orders.

The schools ignore personal finance and business and hence people enter the world totally clueless as to basic concepts of business and finance.  25 years ago when I was financing small investors I made a loan to the purchaser of a small 12 unit apt complex.  

I have updated my cancellation policy to make it clearer to people.

Quote from @Scott Morris: For land, most people use DataTree which requires a subscription. 

It's always good to support local businesses, right?

Both apartments had multiple people living in them who were not on the lease and my property manager failed to do anything.2. 

Not to mention, it's becoming increasely difficult to find people who'll agree to return to the unit to perform repairs due to tenant's behavior.How would you handle this?

Just like VG Jason said, do your own due diligence, trust but verify and run your own business.

@Tip MallickI think there is an international forum but not that many people invest internationally here and probably even less in Thailand anyway.It depends on your objectives (we all have different ones) but didn't you already answer your own question?

I own a rental property (4 bedroom house)  and the Tenant is using the property as his business address for his construction business.
