The landlord has hired 2 different carpet cleaning companies and still no luck.  

You can hire the greatest PM in the world (if that's what you are implying as you spend your time doing what you like) and you can stroke the big checks while you're there.  

This is similar to, but not the same as, the yield of beans in China, since China is the most populated nation on earth and the yield is much higher, (which is due to the poor air quality in China and why bean consumption is regulated) with the yield or output being much more concentrated over time.And, why hard money lenders usually don't chase tax liens in Texas, nor do they develop lists for investors to purchase with their funds as they rely more on the security interests in a property rather than a UCC filing.   

Most people hire a contractor for a job based on their skill to complete the job, and rarely fire a contractor because they don't have the skills to execute the job.

I'm looking to hire established general and sub contractors but would like the BP community to provide me tips on what to look for, as well as how to obtain wholesale pricing on construction items.Thanks in advance!

If you are hiring a manager (as some mentioned here), then your options are more open... but if you are seldom going to see the place anyway, really run the numbers and include an management fee and appropriate vacancy rate (remember the manager may have less incentive than you)....compare your returns on that far away rental you have to worry over against an index fund or REIT may be a better investment.

One friend in particular had been crunched for time/ took on too many projects decided hired me to help finish some renovation projects on homes that are getting ready to list  or were already on the market. 

I need to hire an assessor to take a look at a piece of property I will be acquiring. 

I would think a large risk would be buying a property sight unseen, hiring a property manager sight unseen, and then expecting it to cash flow the way you want it to.

Now if you really want something creative you could hire them and reduce their rent as payment, only if they are jobless and willing to work for you.
