I know, I know it will vary based on costs, utilities, taxes and deferred maintenance etc. but is there a rough estimate that you use for back of napkin calculations for NOI as a percentage of the gross rents?

Take some notes on the back of a coffee shop napkin and do some hard listening.

They require it here for sanitary purposes.  

A quick napkin test I use to pre-qualify opportunities before fully analyzing them or running them through any calculator is the 1% rule.

With the lid closed, it looks cleaner, sanitary,  and protects the plumbing--why would a person not close the lid? 

We signed a napkin saying I could list the property (always bring every document with you!!!!!)

Sanitary facilities and a safe method of sewage disposal.

If they have paying tenants now  I would leave them occupied and not renovate  waiting for turnover unless they are bad tenants or the apartments are not safe and sanitary now.

Very nasty long term tenants who have some pretty severe sanitary issues.

But I was curious - just based on the listing, and the homework you can do vis a vis comps and the neighborhood...... what would be your back of napkin guess for rehab cost, and ARV?
