I can only give generic investing advice. 

Auckland: Penguin Books, 2004.Books on Real Estate Investing – These books outline generic basics of real estate investing, with a bent towards the Buy & Hold crowd. 

Rely on one of the generic online bookkeeping services that advertise simplicity and low cost.

But if this includes coaching calls, education on underwriting principles (please, don't rely on guru/mentor spreadsheets - they are too generic, simplistic and entry-level), post-deal analysis including managing renovation projects and financial reporting - then it could be a good deal.

No offense, but your question is too generic to provide real assistance.

@Leo DonI echo @Travis Lloydand @Daniel Raposo.There is no way you're ever going to learn everything before going forward, so using a generic number (like 3%) might work for the beginning.

If it's the latter, somewhere like Law Depot (online) will have it, but it will be generic.

Personally I'm not a huge fan of JWB (although I've not bought from them) but that is mostly because they throw generic builder-grade tract homes on every low-quality lot they can get ahold of - whose only value is their "newness" - then sell, rinse and repeat.

Products on Amazon do not have reviews and are generic. 

They have a generic sounding name, but they are "The Mortgage Firm".
