So year 5 you're at $500K and if you participate in the next fund that also has similar projected track record you would end up at year 10 (from start to finish) at $1M. 

You sound like you are on an excellent track to drive money into investments in the near future.

Hi everyone,I am looking for suggestions on the best/easiest/cheapest book keeping software to keep track of my books for a few rental properties.  

Definitely if you were able to get it at the right price, you would make a killing.I have two recommendations:Find a local investor and go in on it 50/50 (A slice of the pie is better than no pie and you are guarenteed to succeed if it is a good deal and you go in with an investor with a track record)Find a different home for you to move into.

I'm on that track.

At the same time I feel like security cameras and smart locks you control with a smart phone would take care of most of those worries.You could even try using FaceTime with the applicant for an initial phone interview then ask them to text you a picture of their drivers license in case you or the police need to track them down later.

What is the typical price per lead(or price per deal, whichever metric you track) through the various marketing channels?

Hi John, @John PowellYou are on the right track.

I think that is right but it could have changed and I haven't tracked that figure in many years.

Stick with what you're doing, track your deals so that you have a proprietary database to lean on, and update your assumptions as you go.
