d - Do you have that many properties in your market that will deliver this to you...and do you have the ability to manage, etc... them all, as they build up.

I am interested to know how using a tax-deferred retirement account to purchase a rental would affect my ability to use depreciation.  

IMO, for someone with an entrepreneur mindset, you never have a JOB, a JOB owns you and limits your abilities to change a lot. 

Her ability to move around and manage her property is getting worse and worse. 

On top of that, being able to source the lower cost subs and the ability to take on any repairs yourself if needed is worth a lot.  

(simply elect to not renew with a notice period you specify)2) collect rent on a more regular basis...I find that a lot of folks have difficulty budgeting for an entire month, so I collect rent via direct deposit every two weeks...3) as a last resort to avoid costly turnover, reduce rent to a figure that she can meet that still alows you to cover expenses...once she demonstrates ability to say...pay $950 for two months, raise rent to $1,000 a month for a couple months...then go back to full rent...It would also make sense to verify if she has had a change in financial circumstances and can no longer afford the rent...if that's the case, it doesn't matter what you do...she will continue to fall further behind on payments

@Han Oo Sure...I buy property in an LLC because it works for me...I operate LLC's as sole member and have the ability to make decisions on behalf of the LLC (this works similarly in most states, but you may want to confirm)...I ask my lawyer to draft a quit claim deed and deed the property from the LLC to me...I complete the re-fi, then execute a general warranty deed back to the LLC.

Does anyone know of a direct market company that has the ability to draw a map around the areas they want the potential clients from?

Look at the ability to pay for the tenant, not just rent but a future PITI payment.3.

@David Sanford See if you can get a merchant account with your local bank and give your tenants the ability to pay with a debit card if they want.
