A new vanity is also an inexpensive upgrade.

You have a very detailed breakdown of initial move-in expenses (but you didn't fill out what was received), but then you don't include a detailed breakdown of recurring charges.Your late fee language is completely wrong.

I highly suspect that the reason that high liability limits are relatively inexpensive is because insurance companies have many exclusions to help them avoid paying in the high liability situations.

You are likely going to have to spend more time helping your mom and better to enjoy the quality time you have left with your dad.Go through each property and write out what it brings in, expenses, etc and rank them as to the one you want to get rid of first.

But yes, you're right, the difference between the inexpensive freelancers and larger SEO companies is quite minimal, at least in the beginning. 

To add units is very easy and inexpensive.

If you see a $220k listing for a duplex where each rent is $1000/month you see immediately that this deal is CLOSE TO 1% and that with negotiation or other improvements in rent or savings in expenses could meet or exceed that.

Subdividing the lot would add an additional $20k in expense as I would need to tap city water/sewer to the new duplex (previously the detached garage apartment).

We lived a few miles from campus and the houses were pretty inexpensive at the time.

To date I've been able to account for smaller expenses by tying them to a specific property if for example I'd purchased an inexpensive hand tool for a specific project on that property but I don't think that would be the proper way to account for more expensive tools that I bought for the overall business like a new lawn mower or something.
