We saved him a bundle in inspection fees, septic inspection, and well water testing.

@Alessandro Pascucci your estimates provide a quick and easy "sniff test" if it's a good deal or not.

It will also show if you had the 1% rule/test or not.

And variables like real estate taxes and cap ex potential really weigh performance.On metric worth keeping an eye on is a stress testing of your purchases potential performance against a non-1031 sale and instant tax liabillity. 

Let's face it: 2020 hasn't been good for many industries. 
I feel relieved and excited about the resiliency of the single family residential investment market. I did not believe this was going to happen but we're see...

Not to add to your things to be worried about but.If it is a commercial repair garage during your due diligence period may want to get the soil tested for hazardous waste.You definitively don't want to buy an EPA issue.

I think it’s a good test for when you have real repairs and property issues.

You can target buyer keywords like agents near me, best agents in {your market}, etc, which is probably your best bet if you are convinced on testing ppc. 

The thing that caught my eye is that @Scott Kunz mentioned he might have a tool to sell after testing it and I think for the the cost of development that he mentioned, about $400, it's a great idea to develop what has the potential to produce as much income as another STR.  

But also try to get more info from the realtor. ask him why it has been for so long and and is there something wrong with property  etc etc, or just move on , I typically don't force the gate to open if they want to keep it close  ( metaphorically speaking) Or maybe that's the agent strategy to qualify who he is speaking with and want to test the level of interest or quality of buyer..
