I have a lease created by an NC Attorney; however, I've also made use of the NC Lease offered by: https://www.ezlandlordforms.com - which does allow each addendum you mentioned and reports to be NC Law specific.

Madison has one that meets twice a month which you could check out at www.madisonreia.com  They have about 60 investors meet at any given meeting and typically about 10 brand new investors will peek their head in each month.

Here are my thoughts based on some avg #s$1980/2 = $495/mo x 4 units1 bed/1 bath units typically rent around $400/mo so my initial thoughts are how did they get almost $500/mo for these.Lets say you get $450/mo x 4 = $1800/moProperty Management - $180Taxes - $200Insurance - $100Water/trash - $200Vacancy - $180Repairs - $180Cap Ex - $100Total expenses -  $1140/moThat leaves you with about $660/mo before any mortgage etc....

Rental Agreement + Option to Purchase AgreementRental Agreement: a typical lease agreement with the total amount of rentOption to Purchase Agreement: this includes all the terms of the Lease Option such as Final Purchase Price, NROC (see below for more details), and how much of the rent will be credited back as rent credits (I typically charge above market rents and use that extra amount as rent credits).I have the Tenant-Buyer sign both of these docs and pay me the Non-Refundable Option Consideration (NROC).
