Hey @Josh L.
It sounds like you are in a good spot to get started, having that much extra cash every month you should be able to qualify pretty easily for your mortgages, leveraging your investments will help you generate higher returns albeit with more risk.
Since you do not have a history of renting out properties you will have to jump a couple more hurdles. If you purchase a rental property that currently has a lease you would be able to use 75% of the rent to help you qualify for the mortgage. If the property is not currently leased than an appraisal would have to determine the market rent for the property and then you could use part of the rental income to qualify for the loan.
But if you are able to put $3k per month into savings I doubt you will have a problem with qualifying even without rental income. If you don't need the rental income to qualify it will make everything easier for the mortgage process.
There are a couple other things to be aware of though. You eventually will be limited in your purchasing power because it becomes harder and harder to get mortgages the more you have. Also you would need to pick a loan program geared towards your goal of purchasing a primary residence next year.
I think a good place to start would be to create a plan for how you can most effectively leverage your investments over the next couple of years. Too often new RE investors do not understand how their ability to qualify for mortgages will change depending on your situation. This can end up being a real problem a couple of years down the line.
Let me know if you have more questions that I can help with!
Thx
