I am wondering if transferring the cash periodically to a standard brokerage IRA account may be my best option.

Here are some key elements to include:Lease Agreements: Ensure your contracts reflect the latest laws, such as notice periods for entry or rules around security deposits.Fair Housing Compliance: Familiarize yourself with federal, state, and local fair housing laws to avoid discriminatory practices.Property Standards: Regularly inspect your properties to ensure they meet safety and habitability standards.Tax Documentation: Keep accurate records to comply with tax reporting requirements.4.

Then have a 6 month period to convert all old currency $20 and $100 to new currency.  

You said in your post  "If the notice was delivered by mail then the notice period begins when the Tenant actually receives the notice."

@Stacie TellesMost lenders have a seasoning period (typically 6-12 months since the original loan), so check with your current bank or shop around for others.I would also watch out for prepayment penalties on your current loan.

I guarantee virtually no one is meeting that rule in SD because they're all on here looking to buy in Cleveland or Detroit because in that market price to rent ratios are so askew that buying at a 50% discount probably doesn't get you the 1% rule. 

To throw a wrench into things, if we were talking about real property/structures that were being short term rented, it's possible/likely that your depreciation period would be 39 years, not 27.5.However, a vehicle - which is what an RV is, regardless of how you're using it - is 5 year property.

For a small landlord, it CAN (no guarantee) be better to charge lower rent and approach the landlord/tenant relationship differently.

Most people don't qualify for that relationship.The seller financing will not show up or affect the credit score.However, when applying for a loan at the bank or especially a Federally Guaranteed loan, they ask on the application for ALL Loans, whether  or not it shows on a credit report.

If you have a 2 year work history, and go get a W2 job tomorrow, we could use your base pay right away (as long as it is "guaranteed hours" or considered "full time".
