However, they approach financial health from different angles.The 50% Rule is a quick estimate that suggests operating expenses (excluding mortgage principal and interest) will roughly equal 50% of the property's gross income.The DSCR is a more precise calculation (Net Operating Income / Total Debt Service) that determines if a property generates enough income to cover its debt obligations.Deal example:- Class C middle class neighborhood- 4bd / 2ba single family house- ARV: 190k- Purchase: 105k- Rehab: 35k- Market rent: $1,400-1,525- Section 8: $1,475- Property manager: 10%- Taxes: 125 month- Insurance $1250 yr- HOA: $55 month- purchased and rehabbed with all cash.

Quote from @Russell Brazil:  yep that does it, we lost our home in 99 in an f5 when I was younger,  no close calls recently in OKC though,  also seems like tornado alley has shifted a bit to the east but who knows.

I'm also on the east side of the state.

.), I'd recommend that the residential units fully cash flow the loan as my experience is that mixed use properties are tougher to finance as most lenders tend to prefer one or the other and something in the middle gets more difficult.For example, and granted I don't know anything about the area/neighborhood, I would expect this property (https://www.realtor.com/realestateandhomes-detail/111-NW-Har...) to be easier to finance than the mixed-use property you mentioned. 

All that said, we just met them in the middle and gave them the credit because we wanted it to be over.

I just completed a 1031 exchange where I sold a home in east county in an hoa to do a 1031 exchange and purchase a multlifamily in South Park of San Diego which has room to add 4 more units.

In the markets we deal in, numbers can kill deals that would be home runs elsewhere but a 2x4 costs about the same in both (just the sales price does not support a rehab that would be middle of the road in a place like CA.

The house is on the east side of houston near 2 universities but it is a rough neighborhood.  

If you are willing to do some work, you can force appreciation, capture some equity, which boosts rent-to-value.In terms of areas to avoid, I would stay away from the East side, particularly anything along Post road between Pendleton Pike and I-74. 

It’s the aspen of the east.
