We need the cash to mostly just tie us over untill we sell the property, so 150,000 is on the upper end; 80,000 and above would probably be sufficient. 

Mainly the "self sufficiency test". 

Best" is very subjective and the quantity of off market leads isn't necessarily the metric you should be focused on.

I've been informed that completing the course alone may not be sufficient to pass the exam, so I’m seeking advice on how to prepare effectively once I complete it.Currently, my only other resources include a YouTube video, five practice exams, and a textbook.If you have any additional suggestions—whether online or in-person, paid or free—that could help me effectively prepare for the exam, I would greatly appreciate them.

The learning curve is probably great on importing large quantities or even just large things from a foreign company.

Another possibility could be a home equity line of credit (HELOC), if you have sufficient equity in another propertyGood luck with your project!

I dont think its a quantity metric, but much more a quality metric.

One thing to be aware of is the FHA multifamily self-sufficiency calculation which determines if a property can generate enough rental income to cover its mortgage payments.

If you had good credit (670-730 range), you have 20% to make a down payment, and sufficient income to qualify for the home you want to purchase - Would you choose the FIRST-TIME HOME BUYER or CONVENTIONAL purchase option...which would you pick and WHY?

The best way to connect and learn is to be in rooms where it's going down.In terms of captial your best bet is to focus on a primary income that cash flow sufficiently, saving as much as you can and doing something real estate related so you can get familiar with the industry.
