Think more broadly about students.It may be someone who is older, has a family, works full/part time, maybe even employed at the university, on the GI Bill, etc.

This "smart lawyer" trope seems to be sufficiently broad to negate all rules of law.

It's easier to default on rent than a mortgage payment. 1) DTI is hard to calculate as even one card can have multiple rates (purchase vs cash),2) not all cards have the same rates3) you need the rate to calc the monthly payment dueThen too the DTI is very broad brush and spans multiple years and good tenants with action plays can take YEARS to bring down the DTI - - thus you stereotype over a misleading metric.

Kinesiology....lolIf I could go back I would have done economics or finance, something broad and relevant

@Jason TuroThis is a broad topic with no simple 3 sentence answer to your above questions.  

Trey Moore Your inspector can give you a broad expectation based on the current condition.Roof replacements are capitalized and depreciated.Capex % reserve is what pays for major work on a property, which is why it's important not to underestimate this figure in your analysis.If a roof is at its end of life, you can have a roof contractor give you an estimate of the condition and expectation of future repair/replacement costs needed.

Tenants teach us.With shots fired and weapons brandished, you definitely got one end of the spectrum (the bad end).

A couple two cents here...There is a broad spectrum of risk levels in real estate investing.

if it is not in the lease you cant charge it to them, unless your lease has a broad clause stating that tenant is responsible for all fees billed by HOA. your kindness in letting them out a month early is irrelevant.

The IRS has broad flexibility using the facts and circumstances of a particular case to make a determination if the tax-exempt is substantially acting like a competing commercial enterprise.
