Is it necessary to include photos of the exterior of the property for Airbnb? 

yes, get a mortgage securitization audit done with Bloomberg report included.  

there was a group of 8 of us that pooled money in a Cabal myself and one other were the main money guys the others put in smaller amounts and when we won one.. we would divy up interest prorata to the amount contributed.. this kept those guys from competing against us and for sure we bid up newbies .. really the only ones that would beat us were those that wanted to live in the house and would just go almost all the way to retail or above .. or someone bidding on a second thinking it was a first and no one is going to help you if you dont know what your doing.. this is a very caveat emptar bizz.

I just bought my first rental property in Baltimore, MD, and I’m planning to rent it out by the room, including the basement.

@Nate Pucel The depreciation basis for a rental property includes the purchase price plus the cost of renovations and improvements that add value or extend the property's life.

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).

When all the dust settles, and the  person searching is tired and discouraged and gives up, Jerry may not have bought  a single lot, but he's made some money from the training he sold you, which was his main goal from the beginning!

We’re moving into the ADU ourselves starting in January so we can remodel our main home.

I mainly use FCI and Madison for the majority of my notes.

It indirectly impacts the credit score, which would be included in either metric.
