(With mixed results) cash flow while leveraged was more important at age 30 than it is at age 40.

Old houses have cast iron pipers that will disintegrate (because of age and/or foundation shift).

Also depending on how is home when you knock, their age etc....this could get creepy really fast. 

Replace them as they age out.  

Hey all, I have a general lease and clearly it is outdated with no mention of wifi or connected devices, wondering how you throw in connected/ wifi devices into your new age leases?

Instead of getting a general list, I would suggest you define some criteria, what you are looking for: for instance apt. classes (A, B, C, D), neighborhoods (A-->D as well), age of the properties, size (depending on interest and budget) you are willing to invest in.

Such a great way to start building a portfolio from a young age with as little as 3.5% down.

But with age and family obligations that has been a problem. 

And have them guess roughly the age of each and potentially if how much use each of them have left. 

At this age it becomes a time bomb that you have no clue when it will go.Like the other said. i also have seen 15 yr+ but i also replaced it as soon as i got the house.
