IE installing septic systems in many different scenarios and building a compact treatment plant for a subdivision we developed in Rural Nevada county CA. 

And my speculation so far with the numbers I've ran on the properties I've seen in my area, is that for a typical 4bd 2 bath duplex (2 bed 1 bath each unit), You would need to rent out the other unit (obviously) and even the spare bedroom in your own unit, and even at that you might owe $200-$400 on the mortgage (P&I taxes, insurance, and PMI included though). 

I am going to list the name of the city    please everyone spare some of your valuable time and rank those city with star ( 5 star would consider the best ) This will help all of us for making some good decision for your RENTAL INCOME CASH FLOW!

I'll spare you the details, but a phone call with Baltimore permitting revealed they would love to turn this simple task into VERY expensive enhancement (of which I could find no basis for in all the MD, Baltimore, or International Building Code books).So, I'm curious if any other Baltimore City landlords, rehabbers, or property mangers have ever had a similar experience?

I have a business that never made a profit and a spare house that I'm not entirely sure I want to ever rent out again.If anyone has had success or suffered great loss from these classes I would really appreciate hearing from you.  

I would bump it up in any scenario where I was intending to borrow 100% though...unless you have spare capital as a stop loss.Make sure you keep some cash or another non-traditional-lender line handy as a take-out for that line with a 5-year balloon from the bank.

That should cover you with some to spare.

I have a spare room in my personal home on Airbnb and have had a great experience.

Everyone is "cleaning up a few things". and "Have to get the room painted and carpet in the spare room".

If you have can spare 4 1/2 minutes, here's a video that gives a bit more detail about my situation. https://vimeo.com/249726725Update: I just locked in a new funding option: special bank loan of up to $100k at 2.70% annual interest, payable up to 4 years with monthly installments.
