Are you referring to the SDAT?

Our properties in the Midwest are all large apartment buildings worth north of $4mil so we are looking for a solution that has a lower interest rate of course than credit cards and allows to pay off the balance each month in full and of course pay back the line of credit (or similar) at less interest. 

Like many other cities, you will want to stay away from certain sections until they are better stabilized (check out Trulia's crime maps for reference).

Could anyone refer me to a reliable and reasonably priced electrician?

In that case, then you are getting a landlord policy.If you ever decide to do a flip, it would not be a landlord policy, it would then be a vacant property policy...just for future reference.

Refer to seattle's just cause eviction ordinance for details.If they are on lease, and the lease terminates without automatic renewal then my understanding is you don't have to do anything except notify the tenant you aren't renewing.  

I recently found a deal which is ripe for an owner financed solution, and after talking to the sellers agent he told me to 'write up a proposal', which he can give to his client.This will be my first owner financing proposal, as such it turns out I have no idea what to put in the proposal (a touch of sarcasm)! 

I'm creating a spread sheet today of all my past deals for future reference when dealing with bank and private lenders.

I have personally had many DISASTROUS experiences in owning such properties, and I hate to see others go through such things.That said, if you are convinced that you are going to do so, I'd conduct many interviews with local property management firms, and do a LOT of checks on references, etc.Good luck to you and I hope to see you around BiggerPockets!

Cross reference by the "mailing" address... then send them a letter.
