I know there's a way to create an app for calls and it tracks inbound.

@Shadonna N.It was one of the facebook pages.I use standard lease, but rent as everything included.They usually pay using one of the payment apps like cash app, paypal, zelle, or venmo

Expenses are just estimates and you don't necessarily need to present the current owner's numbers for a loan app.

Personally, I use Tellus App for all my property management stuff.

Use AirDNA and look at the Airbnb app too to make sure you are aware of the price to pay for them! 

Tenant fills out app and pays fee,   you screen in the software, deny or accept.   

Due to the amount of units we have, this seems fairly easy at this point, but wanted to get the BP take on things.What software/app could we use for billing our 4 tenants in each townhome?

We have owned property in Burlington/Dundas ON for many years & the rent controls are a pita but the Cap App is beyond amazing.

I would buy another copy if will be at some point I like the features on their iphone app.

Then we look at historical (if available) numbers for Other Income (laundry, late fees, app fees etc) and underwrite to a conservative estimate of total Other Income.
