If you do not run numbers, you are shooting from the hip and your strategy is either fueled by "hope-ium", or your experience is so immense you know every input and return without running the numbers (but even the most experienced investors run their numbers).Here's the best advice I can give you: You can "run the numbers" until you are purple in the face, and you will never know what every single ACTUAL number is going to be before getting into a deal.

That even though I'm borrowing through an LLC...essentially business to business.

Dymski isn't working, so I'll try this even though I don't think it will work.https://www.biggerpockets.com/users/miked75

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 = 1.23There are 30 year fixed terms and other options such as 40 year with 10 year interest only converting to a 30 year fully amortizing loan.
