Even if you all used the same app, your insight and experience allows you to make a better offer.Personally I would probably still use a spreadsheet just because you can customize it easily and it can do more if you need it.

My wife and I first invested here in 2015 and it was one of the best investments we’ve ever made!

I had a chat with them on the phone as i was curious about the funding.. but came to the conclusion that the down payment ( the client made to buy) was probably what they paid for the property and the seller carry back note was the profit.. and then the seller carry back note is sold to yet another investor.. who is investing for coupon money.   

Mistakes made – Lesson – Learned.

Here's an example why:- One of our people made a mistake last year, and entered an expense of $1500 instead of $150 - they accidently typed an extra "0". - Fortunately, our transparent systems allowed the owner to catch it:)- Full transparency - we would have never caught this honest mistake:(An owner also needs to be involved to approve & fund large expenses: maintenance, property tax & insurance payments (if they want to be more hands off), evictions, etc.A great PMC should also have a chat with you annually about your future plans for a property and your portfolio. 

What made you interested in investing in this type of deal?

I ultimately invested $65 cash, $5k in legal fees, and $9.7k in operational expenses while owning the home, and walked away with $17.3k after a judgement.What made you interested in investing in this type of deal?

It was a subsequent post in response to my question that OP made clear it was because the state required deposits to be held separate.  

It seems as if they intentionally made the breakdown of the payouts difficult to understand.

However, there are instances where it may be beneficial to perform additional cost segregation studies.You could perform a second cost segregation study after you’ve made large improvements to the property.
