The tool would be able to do myriad analysis to evaluate the deterministic analysis such as margin of safety, probability of a return, maximum buy price given a certain probability of a return, and calculate the opportunity cost comparing this investment to an equal investment in an index fund.Does anyone think a tool like this would be useful and beneficial or do you think it's more of a waste of time?

I thought this issue was resolved it is not resolved now I had to have a wall rebuilt that was ate up with mold luckily I have caught the water early this time and cut the drywall back so the only mold food is the bottom wood beam. 

It appears that State Farm provides insurance and four other companies. https://www.statefarm.com/simple-insights/safety/its-not-the-breed-its-the-bitehttps://einhorninsurance.com/dangerous-dog-liability-insurance/

I would consider using financing even if you don't need it to keep cash available for the next deal and to keep a nice safety net.After 2 years of reglar income from this you will be able to finance this business. 

I would go one step further and point out that the food they eat leads to most of their medical problems.

Some food for thought, most successful wholesalers find deals direct from sellers where agents are not involved, most of them do some type of consistent marketing, to find deal leads and most have buyers lists of approved all cash buyers to take them down.

Not just for my business risk, but also for the safety of my other tenants.The willingness to pay rent upfront is also a huge red flag as several have said, but as I state I would not have ever gotten that far. 

Is there food and beverage offered? 

Are these people literally pulling out their IRA's at a penalty to fund a deal, or is there something in the funding and it's just used as collateral/safety net?

Mold needs moisture and food, dry it up.
