I'm coming into my 4th year and to say that I could write a book about my triumphs and mistakes over these years is an understatement.

I can see an occasional mistake, but you said it was pretty much everywhere?

I would like to purchase more multi-family homes and I am interested in learning from other's mistakes as much as possible :-).

I think it may have been a mistake lowering the rent.  

You will save thousands in avoided mistakes.

From not having a lawyer review a lease (that one cost me about 100k) to not getting correct sale paperwork written up (that one hit me aboutu 10k AND resulted in a tax lien) -- if there is a dumb mistake I have probably done it.  

Thank you both for the advice, I am gradually collecting information to help me make smart moves without making too many "trial by error" mistakes. 

I'm of the opinion that managing property is easier than managing tenants, and make no mistake about it, success is dependent on your tenant management skills.Everyone loves cash flow but do you enjoy what comes along with it?  

Sorry, rookie mistake... 

Learning right is better than making costly mistakes!
