I am desperately seeking a trustworthy and savvy property manager to not only manage my properties but to also help advise me on new property purchases.

To be a good wholesaler, first off you need to be able to navigate an incredibly slippery slope both morally and legally contacting desperate sellers off market, tying up a contract with them, and then often times attempting to resell that contract without proper licensing to do so and no ability or intent to close on the contract yourself within the time period allowable by the contract and with the intent to back out if you are unable to.

Are you sort of desperate for contractors?  

(I've made that argument with some success in the past)Above all, don't beg, don't whine, and don't come off as desperate.

They desperately want to text in the car, rather than drive it, and autonomous cars will mean that they won't even have to stop texting during the time they are in the car, meaning that the only times they won't be texting will be when they are asleep.  

I figure if the seller is desperate it may help to let them stew a little bit.

@Easton Enge, I imagine that the answer is "yes", with the proviso that you are using the correct formula for a single family home, which of course is largely guesswork anyway, because every property is unique, and the market value depends on who is looking to buy on any given day and how much they can afford, and how good the selling Agent is, and how desperate you as the Seller is at the time, and how much the Buyers have researched the comps, and (should I go on)?... 

The 10th - 20th is the sweet spot where renters feel the urgency of making a decision but still aren't desperate)

They are desperate to have the first contract go through, and it's likely an opportunity to negotiate the price down in exchange for the 100% EMD.- You mention risk of researching title, etc. 

I was originally going to outsource the interior and exterior paint, patching, and pressure washing for my 1200 SF SFH rental, but I ended up being way over budget on the rebuilding of a room and now am desperately trying to slash my remaining expenses.
