We heard of guests who checked out at the end of their stay and decided to notify their credit card company they did not book the reservation.

I was a RE broker doing acquasitions for a large syndicator in the 80s in San Francisco / Sacramento market.. and thats what brought down their billion dollar buziness taking reserve money from good projects to prop up losers..

What you want to be on the lookout for is the Reserve Fund.

When doing your calculations - be sure to include principle, interest, property taxes (what your new ones will be - not what the current ones are - because after 1 year they reset to what you paid on the property), property insurance, and a maintenance reserve (we use $100/door/month on maintenance).  

Other than that, not factoring in replacement costs, big ticket item expenses, and not having any reserves are some main ones that come up. 

On top of that you will need to show cash reserves to support you can complete the project. 

Keep saving your money and make sure you have plenty of reserves before you buy anything.

I’m dealing with this exact issue as we speak.Here’s the details:Guest makes a reservation through Airbnb.

They also usually require "reserves" to refinance (most loans do at least). 

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).
