I would imagine the best actions would be to immediately fire the management company, pass the keys onto a new one, sue the old one in small claims court for the listed damages.

What steps would you recommend to minimize damages and resolve this issue efficiently?

They are farily easy and do nto require much to get started and the Max LTV is going to be 75% but I have seen some exceptions to 80%.Rates are subject to a few thing like loan amount, property type, number of units, credit score and downpayment.DSCR allows you to purchase with No employment and No tax returns so its a little easier. 

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

Especially if seller just received a windfall from the sale it is definitely worth suing for damages.

@Ali Mol In a lease-to-own agreement, the $1,666 monthly credit should be treated as a liability (deferred credit) rather than rental income, as it is allocated toward the purchase price.

Great credit scores and plenty of income from my W-2 source. 

However, if for example, the company did not install or disconnect the washer and dryer correctly (such as leaving a valve on) while water is turned off prematurely, causing damage, what language do you put in the Lease to also hold other parties accountable such as ALE and appliance install company?   

Reason #1:  If you're not careful even a bad lawyer can get it turned into a purchase, with all of the rent credited to the purchase. 

When getting a DSCR loan whose credit score is the lender going to use?
