I think the biggest component is going to maintenance.

However, I still would do a complete analysis of the life expectancy of all your major components and appliances. 

Talking about how that is detrimental to you would take about 3 more paragraphs.If I knew who your preparer was, I'd be inclined to turn him into the IRS for grossly fraudulent tax positions. 

There is *wear and tear* to replace EOL (end of life) components. 

I'm relatively new to RE, but have recently made up my mind that it's going to be one of the main components to my long term wealth building strategy.

Once the property is under contract I have it inspected to determine the current condition and life expectancy of all major components and appliances.

I'm currently using AmRent for credit and criminal checks and they claim to have a manual eviction search capability but I haven't used that component yet.

Geez man I hate to come down on you cuz you are in a situation , but you don’t even understand the most basic components of using the brrrr strategy .

I was wondering what is more detrimental to structural: standing water for couple of days or rain pouring in over months?
