If you are doing something other than just typical property management with this person/company that would require a lot more money going out than coming in, then it may be a good idea to set them up with a working balance that you replenish as you go.  

My deals typically look like - buy in cash (my own cash usually around 80-95k), I have a local bank that will essentially do a no seasoning cash out refi but they call it capital replenishment, so I'll get 40k or so back, use that on the rehab (or a 401k loan), then refi into a LTR conventional loan.

I cannot possibly add any value to a multi-billion dollar company with my penny-ante investment in its stock, but I can add value for myself, pull out the loan, pay it back when I want, if I want, write off the interest against the asset (which I can charge myself whatever interest I want as I replenish the cash value of the policy ((which didn't actually go down, kept earning interest and dividends)) all for a net effective interest rate of 1.9%).

Either option might drastically reduce your housing cost, increase your savings rate, thus accomplishing a similar goal as a cash out refi, ie you might be able to replenish your cash reserves in a year or two.

Income to replenish 3.

The replenishment doesn't stop.

lets say I want to protect my assets from ...myself, and being afraid that one day I will sell my rentals one by one to replenish the bankroll I decided to lien the property and .in case I sell it ...well then the beneficiary of the lien will take all the proceeds from sale.

You have to do the roof on that house and it costs $7,000, well you had the cash on hand and you don't need the cash flow to live so you just don't make any money for 1.5 years as you replenish your fund.The issue is a lot of people spend all that cash flow and don't have the liquid reserves or supplemental income to handle a prolonged vacancy or major capital repair, so they should be accounting for this and putting away money for the inevitable. 

I leave (2) 3-packs of filters at move-in, and during my visits throughout the year will replenish them for the tenants.

(This would be my fourth rental)     I would normally never deplete reserves this far - just did it counting on replenishing reserves quickly.
