Much depends on the experience of the person your lending to.

Speaking from private/hard money terms, the loan would most likely be considered a delayed purchase if less than ~5 months depending on the lender, and no financing was used on the original purchase.

Alternatively you could possibly look into an SBA loan if you plan to owner occupy one of the properties (depending on your current role and whether its W2 or etc.) 

Every private lender will have different costs associated with getting the loan, which can depend on factors such as LTV, FICO, property type, etc.Private money lenders are almost always more costly compared to a traditional bank because there's much less paperwork/due diligence involved.

A lot depends on the experience of the operator.

It really depends on how you define them.

It depends on the type of loan, loan to value, fico, income, debt, and experience.
