You can start by going to www.narpm.org to search their directory of managers.

You can just do an internet search for Certified 203k Contractors and you will find the national directory. 

You might try using this link for the National Association of Mortgage Brokers.https://mms.namb.org/members/directory/search_namb.phpor google "namb find a broker" and select the second result if you don't like clicking links people post.A lot of mortgage brokers are going to do both QM business, referred to in the past as Prime, and Non-QM, referred to in the past as sub-prime. 

How cool would that be to have a national directory/scheduler of sorts. 

I know BP has a directory for them, but I feel like I have no idea how to decide on which one to try and work with. 

@Cheri Crane You can certainly find reputable HML here on the directory associated with BP: https://www.biggerpockets.com/companies/hard-money

Then look up that llc in your states business filing directory.

I don't use an app or anything online to store documents; I just have directories on my PC, which are backed up regularly to an external hard drive.

You need to go to the old phone directories and criss cross directories down at the public library downtown.  

I don't have any personal recommendations but you can start by going to www.narpm.org to search their directory of managers.
