The rent roll is an accounting ledger that will give you a better idea as to when the tenants pay rent each month, how much they pay(hopefully it's the full amount), any amounts that have yet to be collected, security deposits, and any other miscellaneous fees.The property expense report will give you just that, the expenses of the property.  

Since rents are lower in those areas sometimes you are better off having a tenant in the unit even if they are non-optimal.So placing a questionable tenant at 500 rent a month to only get 1,000 in 3 months versus the unit getting stripped sitting vacant for 10,000 in damages.If this is an average to better area and a good rental time of the year then it might make more sense to wait.I would revisit your marketing efforts on why this is all you are getting for an inquiry.If you did look at this you might want to check in your state if having additional security deposits is allowed.

My tenants just deposit into my bank account or they just ACH.Hmm, I'm beginning to see how all landlords stick to standard rules when it comes to these things.

That doesn't mean that the tenant can terminate the lease without penalty though, as it appears you can continue to charge rent until you find another suitable tenant and then sue the tenant in small claims court for any amount of rent due that is not covered by their security deposit. 

@Bradley Gibson  yup your right.. has no clue how lucky he is  LOL>in our market if you put that up for sherrifs sale there would have been 20 to 30 bidders easy... if you auctions that only required 10% deposits I shudder to think how competitive it would get... you would have many home owners paying full retail as they would have the time to put bridge financing together.

Will you lose the earnest money deposit if you back out from multiple offers?

From a practical standpoint it appears a landlord should be prepared to wait 6 months to clear the existing tenant and/or come to some kind of agreement with tenant to move--I would not call it extortion, but with financial assistance apparently available for deposits, an existing tenant has a lot of leverage over a selling landlord.Are you thinking that DCHA makes the payment to a tenant to relocate them prior to the end of a lease rather than the landlord as well as that DCHA essentially has to sign off on any eviction/termination with cause that is prior to the end of a lease term (and it appears that can only be after the first 12 months?)?

Example: An earnest deposit can be taken in any form.

A few gotchas:1) Tenants might be month-to-month, and could leave at any time2) Leases may be lost or non-existent, making it potentially harder to collect rent and/or utilities, or to evict if you need to3) Is there a sec deposit?

I let a husband and wife (she's an acquaintance of mine) move into a SFH without paying the deposit.
