The one I close on this week the numbers don't make sense to keep as a rental.

They can depend on the person and the property along with a multitude of other factors.

An example is on one permit I had plans for electrical, plans for gas, plans for AC condenser.

It depends on the lender but at a min they must follow TX SML or lending laws in the state in order to compliantly lend in TX, on whether choose to apply this guideline to all types of occupancies or transaction types (non owner investment, second homes/primary residences, etc)80-85LTV on rental properties is only on the purchase for fannie/freddie loans but on rate term refinances its max 80% and cash out max 75% for 1 unit and up to 70% for 2-4 unit cash out conventional.On HELOC's and rentals are up to 70-75% depending on the HELOC investor or product.Its good to distinguish between what the lenders are willing to do and for which product and also these loan products must abide my state law as well as an additiona layer of "overlays," on top as well (whichever is worst / most conservative).

If they don't have vehicles your property will have to be near bus lines or Marta.

@Ibrahim Mawri my main concern is on exit strategy. 

The bottom line of this table tells us the results of cost segregation.

Do not rely on it for legal advice.

For building a buyers list, I’d recommend joining local real estate investment groups, both in person and online.

Again, the BiggerPockets store has some books on this topic, or you can learn about it by watching podcasts, reading blogs, and interacting on the forum.
