My basic underwriting making some standard assumptions on HOA expenses, 20% down, 7% interest rate, 30 year mortgage, utilities, supplies, and maintenance costs shows a loss of about $22k per year if you are self managing.

You now basically have a duplex for sale and that's an investment property.

So you have to create that balance for yourself.I don't think your goals are bad, you are basically living below your means (in an RV) and buying rental properties.

Those would be tricky too, and the properties have to cash flow, but is this basically accurate? 

While you can't use any overage to help your income, you can offset (if the rents are enough) for a 1:1 and basically have no add to the income. 

**Letter of Intent (LOI)**: Though not legally binding, an LOI can outline the basic terms and conditions of a potential deal before the final contracts are drawn up, ensuring that all parties are on the same page.It's always wise to consult with a real estate attorney to ensure that your contracts comply with local laws and protect your interests.

Start by learning the basics, networking, and analyzing deals.

We have a single HVAC system that heats/cools the entire home.

When your rental income is 1.5-2x the mortgage payment - as is typical for highly refined STR strategies - they're basically not concerned about the mortgage payment.

Basically, more than a certain amount of STR and MTR in the same building were considered a hotel and I would have had to have 24/7 staff on site.Were you able to get around that with the local municipality?
