To address this I took detailed pictures from beginning to end of my most recent flip, documenting that we did a thorough job using quality materials.   

The biggest detail is look for a nationwide bank that is full delegated with little to No overlays.

Maybe you saw this from the Tico Times already, but it lays out mostly depressing details on getting a mortgage in Costa Rica: http://www.ticotimes.net/realestate/25-mortgage-ti...Please post back here if you find anything!

And, I think most women would choose a midwife that has gone through pregnancy.Like the OBGYN situation, there is a lot a CPA may not know about the rental business from debiting and crediting some journals and filling out line 242 on some Turbo Tax input form.And, understanding the operating details of the rental business are just as different from preparing a tax return as being pregnant is from delivering a baby. 

The key is a great contractor and a clear, detailed, well-thought-out scope of work.

@Brice Alef-Torrisi To manage finances for multiple properties, maintain separate bank accounts for each property if held under different LLCs to avoid commingling, which could jeopardize liability protection and complicate tax deductions.If properties are under one LLC, using a single account is fine but requires detailed record-keeping for each property.

The best advice I can give you for seeking counsel in online forums is learn how to ask specific questions and provide as much detail as you can. 

If you don't mind, could you go into a little more detail?
