I'd say it really depends on the specific property and its condition.

Of course, if you do any renovations on the property to get it ready for rent, those renovations may need to be capitalized (added to your basis) or might be expensed, depending on what is done. 

I think your numbers on rents are solid, depending on where they are you could see 795, but conservative underwriting at 695 is right on track.

I have 2 dependents and will be the primary caregiver for both my parents and his parents as they age so we want to hustle now so we aren't stressed financially by these responsibilities in 10-15years and are able to maintain the standard of living we have achieved with income from our (now) primary business. 

Of course, there is a fee for this, $250 and up, depending on the size of the dwelling. 

Depending on the size of the property, that may be appropriate, or it may not be necessary.

Short-term rentals in Houston can be profitable, but success depends on factors like location, property type, and management.

It ultimately depends on your individual investment goals and risk tolerance.

I think it depends on your goals and what you want to get out of it.

Second, general maintenance and repair costs depend on the condition of the house, the age of the house, and who is hired to do the work.
