Sounds like you might need to do a 12 month bank statement program and use the rental income deposits as qualifying income.

Do they charge the tenant an extra security deposit?

According to the Fair Housing Act and the Americans with Disabilities Act:Even if a landlord has a no pet policy in place, the law does not consider service animals as pets and therefore the service animal is exempt from such a restriction.Service animals are allowed anywhere a person would go, including food areas that would normally restrict an animal’s presence.Landlords cannot charge a pet deposit or pet fee for service animals, however the tenant is liable for any damage that the service animal may cause.Landlords can require written verification from the tenant’s health care provider that they are disabled but cannot ask for any specifics about the disability.Landlords can require written verification from the tenant’s health care provider that the service animal is needed.Landlords can request copies of the animal’s health records to prove the animal is in good health, parasite-free and immunized/vaccinated.Landlords can write warnings or even evict a tenant with a service animal if the animal is disturbing others, posing a threat to others or causing considerable damage to the property.In other words, you can ask for appropriate paperwork concerning the tenant’s need for the service animal and to verify the animal’s health. 

Pros: - Easier to switch out students - Cash flow still coming in - More flexible overall - Potentially higher deposits if on separate leases Cons: - Potentially more incentive to move out early- More paperwork, signatures, leases, etc. 

😜)Sometimes the money I bring may be enough to buy the whole place, sometimes it will be the deposit, but in either situation it makes it real.Second issue, Fear.The biggest fear I always encounter is the fear that the debt owed against the estate will somehow attach to him/her personally.I find articles from attorneys that most closely meet their situation and while explaining to them that, “unless they personally signed for the debt, they will never personally responsible for the debt.”

So, the terms of your lease should be catered to that, with very strict insurance terms, personal guarantees behind any company signing your lease, requirements that lessee handles all repairs and maintenance, additional security deposits, and I would go so far as requiring minimum review quality for the host, limits on quality of guests they can accept, etc.And to your point about Airbnb not doing background checks, you are right.  

Normally the tenant will initiate their payment, it will take 3 or so days for the payment to withdraw and another 3 or so to deposit into our account.

That is, of course, beyond the security deposit that we have used.

"The bidding starts at <60% FMV>"4) After you get some bids on Sunday and the open house is over, you start going through the bidder list and calling everyone bu the highest bidder offering them to outbid the highest bidder.5) You repeat step #4 until you bid up the price as high as you can.6) Meet with highest bidder and take a non-refundable deposit (specify this as a "condition" of the bid auction). 7) Close.The idea here is if the highest bidder flakes out, you still have a list of other bidders, everyone just $500 or so lower than the highest bidder.

That is actually how they are making money to buy their multifamily properties....by scamming YOU out of the money they need for a deposit.
