The only thing I have an endless supply is time.

It's supply and demand.Again it's your building so luckily you will choose your tenants screen very well!

I would be interested in offering my services as an Interior Designer and/or estimator of rehabs, along with my extensive construction and supply contacts.  

So here you would actually have to pay for an inspection and supply the report to the seller.

Here are some points that may help others in their letter writing campaign:Be professional in you content - get to the point in the first lineDon't draw pictures on the envelopeDon't draw dollar signs around everything - don't draw pictures of stick housesBe yourself - tell your story; example - we are a family business, looking to purchase additional properties for our family portfolio - we can pay cash but would prefer some seller assisted financing, glad to supply references if needed - we live in the area ----etc.Forget the YELLOW thingDon't tell on yourself, don't call yourself an investor - Don't lie - I can settle in 2 days - we are big (like a made up name -) people like to do business with others they can identify with - be humble if that is possible.As for sending letters to vacant houses that are Free and Clear - why do all that research - a waste of time in my opinion!

Unlimited supply of renters.
