You can probably start the education process at 17, then apply for your license once you turn 18.

Just trying to understand what is practical applying the same to a large RV or boat

@Bruce Bennett this is a super important question and it doesn't just apply to lenders. 

But if they don’t even bother to fill out the forms to apply, or get a basic job to make ends meet, or borrow money from family or friends/ somebody else besides you, then they can’t stay.

After reviewing your application, we’ve determined that, unfortunately, we are unable to move forward with your application at this time, as it does not meet our established criteria for income and (other established criteria) We appreciate the time you took to apply and wish you the best of luck in your continued search for a home. 

Courses and webinars are great if you're getting basic information to help start you off, but you'll never truly retain the information if you don't apply it.

Same applies with any other State, check Licensing, BBB or Corp Lic.

If so she can/should apply for a SSN.

If so, do I use my personal bank account to apply for a loan or do I need to put money in the business bank account? 

@Jemini LeckieRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?
