I was looking at him mainly because he is in my area but I had a lot of questions. 

What are other factors and neighborhood I should consider?

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).

Your tenant's friend will probably just draw it from whatever nearby circuit thay can tap into most easily.....So running a new 14/2 cable from the main panel will probably not be easy unless it is really close.

I would factor more vacancy as you might get more turnover compared to other suburbs. 

It is important to factor in all the benefits of house hacking into your calculations, i.e. amortization, appreciation, income, & potential rent avoidance.

I mainly focus on Columbus, Ohio, where big tech companies like Intel, Meta, Amazon, and Google have moved in, boosting property values and job growth.

The main thing is to find motivated sellers before they list their homes with a Realtor.

But, i do have a couple of LLC's, mainly for transferring property to children or spouse when I drop dead. 

That's certainly one of the factors since 1sts tend to have tighter margins than junior liens.
