Are you factoring in capx, and other expenses?

However, the biggest maintenance expense, by far, is lawn care and snow removal.  

So me as a principal broker if commission is 100k I keep it all as it's my company minus business expenses of course.

I just can't make the numbers make sense assuming a $0 capital expense for purchase/install.2.

It's significantly less expensive for a buyer to get it tested during a contingency period, rather than taking the chance and paying thousands in remediation once the deal is done.

So you would take PITI + (any HOA, management fees) and make sure that rent is higher than expenses.

Choosing the most expensive insulation because it's the most energy efficient, should allow you to reduce and/or eliminate costs in other areas.4 - Energy efficiency isn't made up of added costs.5 - Energy efficiency is the product of reducing energy needs, not supplying added energy.6 - Cost effectiveness is a product of maximum use of materials, as in little or no waste.All of the above should be obvious, in parts. 

To the partnership/LLC/S-Corp it should look just like an expense.  

In fact, it creates a lot more expense and time for just that reason.I have used several different database tools. 

But a commuter trades some housing expense for the home and instead have $400 up in commute costs (plus wear & tear on vehicle and lost time, say 2 hours each way - pre COVID - better than 2 hours until normal commute resumes).
