Home ownership is the number one way to build personal wealth.  

Of course, what they won't and should try is things which decrease the cost to build new buildings...

My passion for real estate investing started in college, and I’m particularly interested in single-family homes and multifamily buildings.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Good luck building your new rental. 

When you go to apply for the next loan that loan will still be factored into your debt to income ratio.

As a somewhat new GC here in Sevier county, I am building to hold and building to sell. 

It is an older building, early 1900s, and I can foresee some major repairs coming within a few years if not sooner.

As a DSCR specialist, AZ is one of the 5 states that makes it strict for lenders, so less than 20% of DSCR lenders can touch it.Credit will play a factor, but assuming solid credit, 75% LTV at around 7.4% with no buy down.

States will sometimes have small differences but if it's in the same state it will be the same.Anything that is 5+ units is a commercial building.
