Looking for something like this so that it's easier to visualize all of our real estate and where it is, especially as we expand into different states etc.

I love how your visual includes absorption rate- such a great metric that isn't used often enough!

I can see where it would add visual appeal.

I use a mortgage calculator from this website, I like it because it gives a visual break down of all the payments.

All roof surfaces are only visually inspected.

The second tank has a blue seal on it so we can visually see it hasn't been used.

this is very easy, the higher DTI you have the more important it's for your DSCR to be above 1.10 by house hacking.I mean if your DTI > 40% and your DSCR >= 1.05 , then house hacking is very important.If your DTI <= 25% then not so much.It's your ability to overcome your DTI-ness that makes it worth or not.

Are there any issues that may be a concern with a visual inspection (pockets of water, swampy land, any type of protected grass, etc.?)
