One of the easiest ways to get into rentals is to add a rental unit to your primary residence or to purchase a home as a primary residence and then move out and turn it into a rental keeping your low-interest rate. 

If that house is still available I would get it under contract as soon as possible as a primary residence and then figure out the details in the coming weeks/months.

That helps offset our current primary: older 3 bedroom plus 1-bedroom lockoff, which is rented below market to great neighbors/dog sitters for $975/mo.

I had a difficult time myself in the past qualifying for a mortgage to purchase my primary home because of self employment.Dodd Frank is what switched many independent investors from doing traditional in-house seller financing, to doing lease options or other similar RTOs to try to get around some of the regulations.

The primary advantage for most is the psychological security that comes with believing it will better protect your assets.

And if you do close and have a gain and it's your primary home I'm sure you're aware of both the $500K married couple exclusion to pay no taxes and/or the new tax laws that lowered income taxes.

@Oliver Sparks USDA offers zero down payment loans if it will be your primary residence.

@Mateusz SkibaIf you are occupying your primary residence and don’t plan to move to the next property, you will need 20% or more down since that will be a non owner occupancy investment property.FHA loans are for owner occupancy only, not for investment properties.

I bought my first primary resident home in my early 20’s.

If you are planning to buy a property as your primary at first to house hack (owner-occupied), then the underwriting gets more lenient in terms of ratios.
