Buy and hold is a fantastic way to build generational wealth but you must know how to analyze the numbers and make solid investments.

It has tenants, I have had one month of vacancy since 2012, I would prefer to sell it without an agent, however I worry that there will be dozens of investors wanting to walk through the place, disturbing my tenants, making them antsy and the investors then low ball or otherwise do not generate reasonable offers.What is the best strategy for making sure the potential buyers are serious before letting them in? 

., so far below fair market price at retail that the repairs can be covered as well as your profit and the flipper's profit in its eventual retail sale -- or 'buy-and-hold-to-rent-out'er's profit before they would expect to get it rented -- plus the title search, closing, and any tax costs related to your purchase from the seller (usually split somehow) - and finally, the title search, closing, and any tax cost split with whoever buys it from you.Now, that someone could be you (you do trust you and your repair-estimate abilities, don't you?)

Would I be able to generate a legal/legit Sales contract and/or settlement sheet for the “sale” to the property?

It's been a while now into Cody Sperber's fast track program learning how to wholesale real estate online, but I haven't pocketed any profits yet besides the education.

I was going through this old thread and a wholesaler noted that she sells at her contract price with no markup, but a 50% profit share. https://www.biggerpockets.com/forums/93/topics/174983-virtual-wholesaling?

Basically, it's as if she and you are both starting at the beginning of your RE journeys, to find out whether she/you would be better off investing for appreciation (eg. buying property that should be ALREADY worth more than you pay for it, AND it's due to keep going up in value too, but, won't generate much net cash flow), or, buying for cash flow (in areas where appreciation has not happened historically, but are still golden egg locations for double digit net rent returns). 

@John Kilduff I actually know a wholesaler in DE that runs an apprentice program where she trains new wholesale investors to know good or bad deals, find leads and close on the good deals with them and splits the profit with them but I only know one buyer in NJ who buys in Burlington county but made I'm with it.
