Projected CF after the first year is $650 after PITI, Vacay, Repair, capex, Etc.Purchased under market rent as tenants were paying $880 m/o.

How should I handle the necessary repairs?

This presumes you make smart purchases that cash flow after paying all their expenses (Principle, interest, Taxes, Insurance, and a maintenance / Capex reserves).The risk of leverage is if your properties AREN'T making money - maybe you misjudged your income, or you run into repairs that cost more than you expected or budgeted for.  

Does anyone have investor friendly plumbing companies in DFW area for sewer inspection and repair?

Short term rentals seem to be the only way to have a positive cashflow after keeping aside money for repairs, CapEx, vacancy, etc. and still have a decent CoC return.What do people here think? 

Operating Expenses (30-35% of Income)Rule of Thumb: Allocate 30-35% of your rental income to cover operating expenses such as property management fees, maintenance, repairs, utilities, and insurance.Why: Properly budgeting for these expenses will keep your properties well-maintained and avoid unexpected financial strain.3.

@Russell BrazilThe seller will not be able to repair.

In the lease state that they come with the unit, but if they break, they will not be replaced or repaired. 

I would say very honest PMs who walked my Indy properties (after the I closed on the homes) or at least knew that neighborhood and an honest construction management company were very helpful - they all said I better add in a lot more reserves to the repairs and cap ex for old Class C.
