Obviously things can vary by state, but this is perfectly legal in my states of business.

Currently I am 22 years old and recently graduated with my business degree and luckily no student debt.

I am sure it varies from investor to investor, but I am personally least comfortable with estimating insurance costs than other finer points in a valuation (management fees, construction costs, maintenance costs, taxes, etc.). 

Taxes also can vary town to town, but are generally high in that county.

I've seen greatly varying costs to remediate mold so it can be hard to say without seeing it.

A detailed assessment of existing systems will inform the type and degree of renovation needed.

The experimenters had subjects flip the switch at will, and they varied the light on and off.

. -- I have done $10k to $50k EMD-- Check with your title company, varies from state to state 

Things such as taxes, insurance, property management & landscaping are relatively stable but will vary per property.

Make sure you get full pricing from any of PM you speak with ---- they tend to vary (i.e. one could be 10%, but there are no "add ons" so to speak, and another could be 7% and have alot of additional charges).
