I prefer those documents to be sight-translated... that means the document is read from the source language (in our case, English) and interpreted verbally (for spoken languages) or visually (for signed languages) into the target language (the language of the tenant).

I will be the first to tell you, I am not a fan of the traditional real estate agent/ client dynamic, but I do think it's important for any investor (especially a new one) to have a professional double check their numbers.  

When people feel like they have no options and they feel forced to do something, they will often lash out.Regardless of the family dynamics, I think the powers that be need to get together and figure out a way to move T into a new place. 

Sometimes you need to "zoom" in rather than trying to process the whole picture and trying to visualize all the steps at once.

That's easy - market share and market dynamics.

I check for signs of plumbing leakage in the kitchen and baths and do a visual inspection for any noticeable damage.  

The refrigerant leak can be the biggest challenge - they must examine the tubing visually for signs of damage, leak-check the joints, coils and tubing using an electronic leak detector, and once they find the leak, the system must be depressurized (pumped into a refrigerant container), the leak repaired, then the system must be evacuated to make sure it holds a vacuum (verify no more leaks), then dessicated and recharged.

This is when a nice spreadsheet will help you visualize your cost/benefit analysis.

Is there a test to see if I'm better off replacing boards or is a visual inspection enough? 

For example my spreadsheet list on a home that rents for $1,000 the rent from the 1st - 5th is $1,000, from the 6th - 15th its $1,100, from the 16th - court date is $1,325 ($1,000 rent + $100 late fee +$125 court cost+ $100 reinstatement/admin fee).This gives them a visual picture of what they are going to owe.
