I am 22 now, I dropped out of college simply because I don’t believe in the student loans and knew I could do big things without it and always had an eye on real estate.I started up my own contracting LLC as I have a construction background of about 5 years from concrete to roofing and everything in-between.

Finding buyers is easy, simply look up all cash closed transactions over the past 12 months and find entity names that repeat multiple times.

“The request was simply missed by our repair and maintenance team”.On January 13, I had to follow up with Company B to close the request for a refrigerator, since I replaced it on December 27.This seems abnormal. 

We do not show a single sign of desperation, in fact we often come across as very "whether you sign or not I don't really care"... not on purpose... simply because we have 376954728529473 thousand leads we still need to make offers on and if they don't accept the price we TRULY do not give a pooples!

you will find on the open market.. set ups like this will have few takers for the note..note investors will look at this as a cash out sell you the property type deal.unless you keep the NOTE VERY low LTV and give a great return.. but you may find a note newbie that will bite.. but note investors that do this for a living wont do it at least those I know wont.you would be just as well to find someone to do a cash out refi.. but in practice if you want to try.. simply have the title company prep a mortgage if its a mortgage state and a note and record the mortgage like any other loan.. 

The buyer may not pay, doesn't pay taxes, wrecks the place, etc.Legal action is possible but also takes time and money, that can be spend better elsewhere.So my question is simple, is there some sort of insurance/service that simply guarantees me that I recieve all my monthly payments?

The time and effort you will spend managing, especially during the first few years when you're learning the ropes and all of your state's land lord/tenant laws and best rental practices (advertising, showing, screening, writing a lease, scheduling maintenance visits, etc.) would make your time more profitable to simply spend working at Wal-Mart as a greeter

How do you estimate cleaning cost, is it simply a multiple of projected occupancy?

As far as landlord retaliation, it would be illegal to retaliate simply because they asked for reimbursement.

All real assets have investing dynamics of cashflow, appreciation, tax favor, and debt pay down (if leveraged), so if you are looking at an asset that has VERY strong cashflow but lower appreciation, you'll simply want to know that going in and compare it to how another asset that DOES appreciate would perform.In my market there is usually a direct correlation to cashflow and appreciation.
