I love the idea.

Of course, you want comps to be as close to identical as possible in terms of sq ft, beds, baths, rooms, acres, garage, etc.Give me a call if you want and I can give you an idea of the ARV of yours.  

Ok my friend asked me about his idea  - to set up a business to offer landlords upfront payments for their future rent checks at a discount for example rent for year 12,000 - he would offer 10k.

If anyone has any good ideas about how to move forward, please share!  

Great idea. 

They should have a good idea what rents are.

Good idea on the phase one.  

I ran through the house with an inspector and a contractor to get an idea what we were in for and figured overall we needed to put about $50k into a rehab (this includes contingency $ just in case).

The attitude is one of collaboration, group sharing & learning from each other's best practices and ideas.

I always like to talk real estate if you ever want to share ideas.
