My son is suffering from a medical condition that requires large bills.

The IRS cross-references your 1098s with claimed deductions, raising concerns if discrepancies arise.Private Lenders and Forms 1098: Private lenders are required to send Forms 1098, but only if they meet specific criteria:The private lender operates as a “trade or business,” distinguishing professional lenders from casual lenders like friends or family members.The loan is issued to an individual or a disregarded single-member LLC.The loan is a mortgage secured by real property.The annual interest paid on the mortgage was $600 or more for the previous year.The conditions leave some room for interpretation, particularly regarding the “trade or business” clause.

Per what I read in the Landlord/Tenant Handbook for Georgia, the Tenants have 7 days to pay after receiving a NTQ, but quote: "the landlord is only required to accept a late payment once in a 12-month period."

The requirements to become an Agent (although not difficult) does take some time and then there is a multitude of fees to pay once you join an RE office. 

The Minnesota agent should be able to write the policy BUT they might have guidelines on their rental dwelling policies that require the owner to be local and therefore looking after the property.  

The 800 a month includes HOA, water, garbage and Insurance.

I do not have a specific pest clause in my lease but I struggle to see how someone bringing bedbugs into my property after 6 months without them, admitting that they likely brought them in and having a professional opinion stating as much would then require me as the landlord to be on the hook financially for removal?

@Qiong Yang If one unit satisfies your reinvestment requirement to purchase at least as much as your net sale then any amount over that can be used for your primary residence. 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Whether you're a seasoned pro or just dipping your toes in the water like me, I'm a firm believer that our collective strength lies in lifting each other up.Nestled in the serenity of Grass Valley, I'm eager to forge bonds with fellow locals and cultivate a network built on mutual support and collaboration.
