One dog may be trained to perform one task (alert to low blood sugar in a diabetic) and the other dog may be trained to perform DPT for autism etc. 

I Personally think that it depends on several factors, blood alcohol count!

Tenants may not be aware (some are) but blood sucking attorneys are.

@Katrina Cebrian I’m not sure why you’d even consider this person unless you like patching holes punched in sheet rock, repairing doors ripped off their hinges and cleaning up blood stains in your carpet.

I can't do math without the correct level of caffeine in my blood :-)

I'm about to run out the door to give blood (the exciting life of a retiree, LOL!). 

There are glue down systems as well but those are thinner and you have to worry about having a level surface before installing.

Other players will play more conservative and pick and choose their spots to play in and grind out a steady profit albeit a likely lesser return.Same principles go into real estate - there are people that are leveraged to the max (and lets assume they're making good investments which is a big if), they're pushing thinner edges with more risk to get the maximum returns.

Although mobiles are easier to repair, many of the parts are specific to mobiles such as thinner doors with odd sizes, skirting, shower surrounds, etc. so you have to buy them at a mobile home supply store which can sometimes be more expensive.We purchased several mobiles (with land) with the intent to rent them out and ended up just selling them owner finance.
