Special thanks goes to Google Voice, my visual voicemail phone app.

It is a deterrent for a tenant to leave mid lease so that helps a bit.

(Im more of a visual learner so like using examples).Purchase Investment property for $250,000 (non occupied) with 20% down payment (loan amount would be $200,000).

The RE world really needs a comprehensive visual analytics tool. 

Currently I have a single one and am looking to acquire a 3 or maybe 4 flat here in Chicago, or another couple of properties in Kentucky.There are a few things l'd like to have:Tenant portal for announcements and service requests / status bits and paymentsMisc expense tracking of consumables for a property for maintenance and general upkeepTrack recurring costsSome tools to visualize the cash flowsI could do it manually, but know it would be possible to, for a given property, generate more or less the total ROI ie: "Over the past 4 years, this property has paid for itself and generated $YY in income" or maybe "When full, this 4 flat generates $ZZ worth of income, but averages $BB in expenses due to maintenance", etc.The other option, which I'm entirely comfortable with (I'm a software engineer by trade and have worked in this industry for 10+ years) is simply writing my own and likely then open sourcing it (aka giving it away for free).What are everyone else's lists of "must have" vs "nice to have pony features"?

I love the visual and steps, very helpful. 

If the city stops by and sees you have that ADU they will leave a note requesting a visual inspection and you will be asked to take out the kitchen and shower from the place and remove anyone living in the Unit. and Housing might get involved...Also Guest cant stay in a place longer than 27 days in a Guest home. 

In essence, it's basically a visualization strategy that I am constantly doing without really thinking about it.

Anyone trying to start a lawsuit will need to pay up early in discovery simply to try and tie you to the property - a pretty strong deterrent to law suits.4.

My attorney feels this is a MAJOr red flag2) the seller does not have proper pay history on current tenants stating that the property is so small they did not keep this kind of documentation. 3) I saw the property and it visually looked good.
