Your vacancy expense could be quite significant and consume all of your profit and even get into your principal.

We have used various methods to save up for down-payment funds: we set aside pay raises instead of consuming them, re-enlistment bonus sums, tax-free income from deployments, an inheritance check, the tax-free savings account while deployed...And so forth.

New electrical, plumbing, HVAC, insulation, drywall, floors, kitchens, baths, the list could go on forever!  

This issue is still being resolved I believe.A L/O that is with an occupant and where rental credits are applied is a financing agreement, you need to follow Dodd-Frank and Predatory Lender Laws with consumers (your tenants).
