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).

But ya have to make some educated prognostications in life.Add this to the information your processing - What your talking about doing is eliminating around $4000 or interest expense (which is deductible anyway so really could be a real impact of eliminating $2800 or so) of debt in exchange for paying over $10K in capital gains tax (don't forget possible state gains tax as well).  

The current average rent on the new buy is $925.

You likely only made a down payment of 3-20% ....but you still get to write it off on the full value across 27.5 years.So 400k/27.5 = 14,000 ish a year of a write off where during the year you didn't need to incur an actual expense, no cash outflow. 

A popular Excel template is Vertex42 as it automatically includes spaces for property details, rental incomes, expenses, and a summarizing sheet.

Real estate investing is forgiving; the average person can still make money even with some big mistakes.

That's including high Baltimore property taxes, expenses, mortgage, etc. 

This may be expensive and not worth it but having it legally split, may also increase value. 

The paid version for sales has a lot more is not crazy expensive for a SaaS.

However, non-government employers on average last less than 20 years.
