If a tenant fails to give proper 30 days notice, when does the clock end for loss rent that I can charge them?

Those that went "bad" had a major life event they could not recover from - job loss/rental assistance loss. 

@Joel Owens, there are a couple of scenarios where "risk of loss" and inventory activity could trigger the gain. 

Each of my properties is under its own llc. you do make a good point about even distributions, but you can have one yearly distribution, or loss. llc's income/ loss are reported on personal tax returns. you can write a check whenever you need the money, if it is available. this is from Entrepreneur Members are compensated using either distributions of profit or guaranteed payments.

Always be sure to contact your insurance company as soon as possible in the event of a loss as there may be limitations on the time frame for reporting a loss/filing a claim.2.

good luck... sounds like you have a pretty high bar to get across.sinkhole is  an insured loss  FYI I have funded well over 150 deals In Orlando last 3 years never lost a one.. but in reading our insurance policies if one got swallowed up then the insurance company owns it.there is no Utopia in rental house investing..

When a borrower has a history of receiving rental income from the subject property since the previous tax year, the borrower must provide most recent Federal Tax Returns, including IRS Schedule E, covering the previous two (2) yearsCalculating Effective Rental Income � Any net rental income from the subject property must be added to the borrower’s qualifying gross monthly income after averaging the reported net rental income/loss reflected on Schedule E of the tax returns.� When calculating the average net rental income/loss, any depreciation, mortgage interest, taxes, insurance, and HOA dues reflected for the subject property may be added back to the net income/loss.� If the borrower has owned the subject property for less than 2 years, rental income/loss must be annualized for the length of time the property has been owned.

Consider the loss part of an education.

http://www.rentguardus.comThey provide tenant screening & rent loss insurance - 3 months rent for 1.75% of the lease value for tenants they screen\approve..A great idea and pretty good value if it's legit and their screening isn't too restrictive.

Our goal was to retire with as little loss in actual income as possible.
