This particular property that I looked at is managed by a PM company and it has bad reviews especially for cleanliness.

And if they are a hobbyist/part-time builder, then they should engage the proper professionals, i.e. a title officer, civil engineer, architect, contractor et al to assist in reviewing the project's feasibility.

Reviewing this will help you get an understanding of who they are. 

A lot of these folks dont want to share their own distuation out in public, so it may be a bit less "social" imo. but creating content around you buy houses / seller reviews and explainng the process at the very minimum will add a huge credbiliity boost to your website and will warm you a lot of seller leads before you ever speak to them!

As lenders, well issue a prequal/preapproval letter if we've analyzed your income, assets (bank and brokerage statements to establish that you have the liquidity to afford the down payment, closing costs, and reserves), review credit of the guarantors, review the relevant experience to ensure that we're not throwing our money away on newbies that are wandering around in the dark, and have put together a reasonable plan of attack for the project.

Full application review is almost more important than lease review, as you are seeing.  

Did they require you blueprints and plans be reviewed and made to conform to their standards?

They take weeks reviewing things and won't call you or tell you when they have reviewed things so you are constantly calling and then waiting for them to find your file.

Every PM I've met has at least several bad reviews, but I'm hoping this helps.
