All are doing well. 40% net/annual (about $50k) and 10% COC. 

Let's say you want to net out to an 8% cash on cash return day one, grow it to 11%/yr once value-add play done, and maybe jump to 20% average annual return on exit.  

I am also going to required annual increases in rent based on the CPI index, among a few other things.Does anyone have experience with this?

If the property appreciates at the expected 5% annually (a reasonable assumption in many parts of Florida), that's a $20,000 increase in value on a $400,000 property.

Often times I see investor clients spend way too much money on fancy entity formations and annual filing fees. 

don't keep a staff. there's a general contractor in our market that has 400 million annual revenue and 41 employees. 10 million per employee. do the math. that's columbus ohio. construction management is the key. get to know the subs, process, build clients, focus on what actually get's business not hiring when you are small. 

:PFrom my experience in the mortgage note lending world, your annual yield should be closer to 20% since you are getting fees for underwriting the deal and paying off the deal.

Returns can range from 4-6% annually.

@Brian Hunsaker sure a paid off property netting you ~$10k annually, or ~$15k before depreciation, sounds fine.The potentially "silly" way to reduce your taxes is to leverage out your properties. 

I only received verbal information on annual income and credit score of the tenant.
