Almost nothing on the market there will cashflow while you live in it with LTR, so try to airbnb the units or do furnished rooms for rent, etc.

What was the cost to furnish?

I'm not sure of what the rules are regarding agent-client confidentiality but without naming any names or addresses, for example:SFH#1 or Duplex #1, if this is Class A, B, or C area, purchase price, down payment, loan terms, monthly payment PITI, gross rent, property management fees, other repair or cap ex costs your client went through and the net rental income for this investorIf this isn't an LTR but an MTR or STR, now we're adding utilities, WiFi, furnishing the place, higher PM fees.

Namely, appliances, flooring, furnishings and updates. 

Or at best you overpay and the "designer" buys the cheapest junk furnishings possible. 

When renting out furnished rooms, am I obligated to provide the exact furnishings and decor shown in the original listing photos?

I was able to replenish emergency fund money I had to dip into for furnishing, was able to pay off a hot tub, was able to replace 2 garage doors and paid for a larger repair this year.

the costs for the Airbnb furnishings could be anywhere from $20K- $30K.. are hard money lenders willing to include this amount in the initial loan? 

I think you may have a run on Vegas props and Vegas furnished rentals Just sayin.Oh yeah, there is soooo many trailing effects not mentioned that I think isn't in minds yet, understandably so, fires are still ongoing. 

For us we all typically use 0% business credit cards to furnish the property which can amount to $40-$60k+ depending on how crazy you go.
