I think it really matters on your personal goals and circumstances.

Units of property that cost $2,500 or less can be expensed immediately for tax if (1) they are also expensed for book accounting, (2) an expensing policy is on file with the company/business, and (3) an annual DMSH election is made before the due date (including extensions) of the tax return.The SHST is an expensing election that applies to real property under very specific circumstances.

Borrower will keep the Property availableprimarily as a residence for Borrower’s personal use and enjoyment for at least one year after the date of thisSecurity Instrument , unless Lender otherwise agrees in writing, which consent will not be unreasonablywithheld, or unless extenuating circumstances exist that are beyond Borrower’s control."

As an investor you should not use these banks under any circumstance.  

Well maybe, depending on their circumstances/goals, they're BOTH right!

Under no circumstances would I let a tenant complete work on a rental unit.

I am looking at either a single family home to do STR (for max. income and cashflow) or a Multifamily LTR (triplex and up to even 12plex etc. ) In all circumstances the deal must work and everyone needs to get paid each month at the end of the day of course. 

It's based on individual circumstances.

By asking this question, I get some context around circumstances that may cause that.

@Bruce ParkThe 811 contacts should lead you to dig alert.https://newtinb.digalert.org/direct/newTicket.htmlThere are private companies that do it as well if you have an exigent circumstance.
