What we do is order a subject 2 aka ARV appraisal and the bank finances 80% of that value plus allowing you to hold your 20% down payment in an escrow fund.

Do you by chance have a prepared document outlining the actionable steps to going from say 'poor credit,' to getting a mortgage?

What is your opinion on this subject? 

My lender is more concerned about the appraisal report which in many cases make the value subject to specific repairs and improvements( if the lender is selling to fannie and freddy).

Very subjective..

I have seen one-page contracts that investors seem to use with one sentence Subject To Financing or Inspection.

If anybody can help me get an outline of start to finish articles to read, videos to watch, step by step, I would greatly appreciate, this site is full of great people and I hope one of you can help me out.

A good lease outlines how a landlord can enter a property.

Further more, if you do not have an interest in the property you cannot market it for someone else unless you are licensed to do so and have an agreement with that person to do so.I will leave the morality of the practice up to you since it is subjective and dependent upon one's moral compass, or lack there of.

This subject is a frequent discussion here on the forum, I suggest you search using this keyword and you'll have plenty of material to read, will keep you busy for days :-)
