.* age 44* 40 doors all managed by myself* net passive income per month approximately 27k* just achieved my golden number of passive income / month last month after almost 10 yrs of hardwork.Now i am confused on should i expand further or just chill and enjoy my life.

When you ask a bunch of old farts what they would have done at your age knowing what they know now, you're really going to get some good stuff.

The 50% rule a good smell test, but the age of the properties, the differed maintenance, the utility break down, rent amount, etc will all change the percentage of expenses on income. 

This would be solved by having the online version, but I prefer the lower cost and not having my data stored online.I use Rentec Direct for tenant screening only- they do an SSN verification, credit, criminal, and eviction check for $29.45. 

I have been reading about real estate since I was fifteen but I never had a chance to put into action due to my age; however, this summer I took an internship at some brokerage and I have decided to become a real estate agent.

Additionally, for a Rule 506(c) offering, the investor must provide verification that they are accredited.

Looking at statistics such as median income and average age, while considering how the area may change in the coming years (businesses coming or going) can be a good start.

If they are VERY professional, they will have their processes in writing as verification that it is enforced equally and fairly by their entire staff. 6.

You can even do loans on investment properties without income verification and without pre-pay penalty on non-agency loans and the rates are still lower than private and hard money lending.

Without knowing the type of house, the age, the scope of work, the level of finishes, the type of contractors, your negotiating skill, the time of year, etc., nobody is going to be able to give you a $/sf average.
