What I have noticed, however, is that most duplexes within a decent price range are completely rented out!  

Buyer is responsible for all escrow fees typically ranging from $850 to $1,375.

The home inspection report states that this is sufficient for each unit.What would you do?

As we grow, I intend to take further measures but since we are just starting out there is really no reason to get crazy since the Umbrella is more than sufficient.

What would be considered sufficient equity in a property?

These are typically bedrooms without sufficient fire egress (e.g. an attic bedroom with no fire escape; a basement unit, etc). 

 @Stanley Kong I just received 1 month notice in my duplex yesterday and I believe I will list for 1200, I try to Keep things clean and performing well and it will be at the top of the range with a monitored security system and dishwasher.

He simply wrote a few smart comments and said he left 9K left on the job for me to pay (Even though it needs 20K total left to pay out, and that should be sufficient, and he said he might look around for a few fixtures he can throw my way, GOOD LUCK and Bye...So I have worked with this same contractor on 5 other fix n flips and we had a great relationship, and he talked about his faith and I thought he would at least try to make it right or at least apologize for spending 10 months on this job and he was sorry he dropped the ball, but he didn't.. he just said Good luck while I take the money you gave me for materials..

I am rehabbing a house that should appraise in the $140-145K range after renovations.
