Apply for your EIN through the IRS using the link here: https://www.irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-onlineIt doesn't cost anything.

Should you allow them to look at the place and filled out the application?

You can use the standard rental income form or I believe IRS prefers it to be taken as self-employment income (schedule e / schedule c) which if is a loss, can be deducted off your regular income, however if positive may incur paying more.

When you use a Self Directed IRA to fun the down payment and the rehab of a project and then when you give the ROI back to who you got it from, can you give it to them in cash or a check instead of the earnings having to go into the IRA.

Be ready to go with the application, lease agreement, etc. 

Specifically, since the mortgage is a self- liquidating liability, funded by tenants’ rental payments (assuming, of course, at least “break-even” cash flow), this new equity never came from the owner’s pocket.

You are required by both state and federal law to remediate any lead-containing products (paint, putty, etc) and obtain a de-leading certificate.If you have a handicapped tenant or applicant, you may not refuse to rent a unit to him or her.

From the things that are required on their applications, you may get additional ideas on what to require or exclude.  

These clauses are contained, in all Promissory Notes nowadays.
