I want to use every method starting out but by no means would I want to waste my time doing a task that will not lead to any new business or calls from city officials.Thanks!

I don't prefer the 'trial by fire' method when it comes to investments. 

You shouldn't have too much trouble finding an SDIRA provider that doesn't charge for incoming funds no matter what the method of deposit is. 

My wife and I have been using the BP method of calculating operating costs for rentals in Houston but we were starting think that just using say 8% for maintenance, 8% for vacancy, etc is fine for a place that only commands $1000/mo in rent but really penalizes a place that commands $3000/mo in rent making it impossible to find a good deal.

If no, you have to find another method - Subject-to, private money, etc.

I run a legitimate business and employ high quality guys that want to be paid fairly for their skills.  

All those other visas will not provide with the employment authorization security and flexibility you will need.I hate to burst you motivation and spirit, and say it cant be done.

What method would be best for noise and most typical for fire code?  

What is your most successful method of finding the perfect deal?

I am just trying to be proactive in my approach and get the ball moving while still employed.
