@Naveen Desai Yes, the property taxes are typically 2%-3% in the DFW area.

Believe it or not, you missed a few:Number of petsNumber of homes with/without garagesNumber of 1 story homesNumber of renters with childrenNumber of renters with jobs in the governmentNumber of speeding tickets given out at the main intersectionsList of favorite colors and how many of each. 

Typically it is the local building and zoning with a similar rule, repairs of more than 50% are not prohibited, But if the rebuild/renovation cost is more than 50% of the property value then the property must be brought to Current building codes, which may include the floor elevation being raised to current building requirements, which is usually not feasible, cost wise.

I don't have as much of a feel for lot sizes, but it seems like understanding what size lot typically corresponds to what number of bedrooms would let you know pretty quickly if there was room for an addition. 

   - repair is typical for an rental occupied property.My view is:  typical for turnkey properties, low performance, defered maintenance that yoiu'll get hit with typically sooner then later. 

Can anyone in the area share with me the typical time it takes to rent out a house? 

- you typically say "I'm a real estate investor" and then continue to qualify that with how you locate and acquire / syndicate multifamily properties with outside investor money. 

I would discourage you from buying condos as they’re typically really High in HOA fees which is completely outside your control (major negative) and usually not investor friendly.

You'd have to look at proximity to panels, metering, etc there too as you'd have some load (copper wires) to likely pull.It typically costs a lot more to heat using electricity vs NG, so I guess you'd be passing that along to the tenants?

You may need a co-signer if you don't have W-2 history but November - January are when you will typically see the softest market.
