(Yes, I will be backing into my goals) but I also want to review how leveraging will impact my cashflow over multiple rentals etc.

Houston is by far the most tied to the industry and therefore would be the most impacted by elongated dips in O&G pricing.

We only have one body. 

For example, look at auto deal association trade publications, they often have classifieds with dealerships for sale, paint shops and body shops for sale or lease and those seeking opportunities.

theyll help you with estimating what it might cost per unit)-actually visit the property (with someone knowledgeable) and assess the condition of the expensive items (roofing, heating/ac systems, foundations, plumbing/elec, etc).some of these things will most likely be req'd by whoever your lender is anyways. of course some sellers wont oblige the requests for such detailed info until theyre confident in your offer/ability to purchasealso, sometimes people only look at their buying plan. you want to have a further view and have a plan on exiting (selling it when youre done). how you finance it can impact this because youll want financing that's favorable not only to yourself but to a future buyer as well.being able to sell it off as easy as possible is an advantage and you should always think how you can approach a property thinking "how can my actions help the property be worth more in the future and ease such a sale/transfer when im done?"

So every body type has it's advantages and disadvantages........ : ) The shorter person has to really get down the kick and mechanics more for stride efficiency.

Since lease turnover controls your timing, it usually take at least two rent cycles to make a significant impact.  

Lastly, It  doesn't account for regional differences in costs so those in low wage markets may see a big impact on the cost of goods and services.

While the areas with bad schools and perhaps some crime issues like the gentryfying neighborhoods in DC...Petworth, Brightwood, Ivy City, Brentwood....will have huge price variations based on the condition of the property.Now do flips happen in Fairfax and Montgomery County...sure, but in nowhere the same types of numbers that they happen in DC and PG County.It doesnt really speak to Dunkirk exactly, but I hope it sheds some light on how doing X, like rehabbing a bathroom could have a huge impact in location Y, but no impact in location Z, and thus why you can not really have a rule of thumb that spending A will return B. 

On the weekends, I let my body recharge and sleep until it wakes itself up.
