I include a self-addressed stamped envelope so all the tenant needs to do is put their check or money order in the envelop and send it back. 

@Adrian Chu i rent a 2 bedroom 1 bath with about 800sqf for 2170Bills included.

If someone is imagining that there is an additional room to sleep in that isn't pictured they have only themselves to blame.The kitchen is 70's with harvest gold perfectly preserved countertops, there is faux wood paneling in every room including the bathrooms.

Its in a town we have a restaurant in i do mainly restaurant business, and have 1 sfr ( manage 3 srf including my own) at the moment but just recently discovered this lot off market someone trying to get rid of it yes new construction is possible yes i know contractors that will jump on it right awayJust mainly want to hear if bulding a brand new 4plex i can rent out to out of town workers on a month to month basis is worth while at a cost of 275k for 200-250 cashflow a door a month at a 15 year loan is worth it?

Also, don't forget to include CapEx and Maintenance!  

For example on a house I'm looking atCost- $310,000- 4BR, 2Bath DuplexMortgage (based on RedFins calculator)-  $2,008 / month, which includes taxes and insurance. 

And lastly, include a right to first purchase for when a partner may be looking to get out. 

Before closing, I made sure prorated rent and security deposits were included on the HUD; however, the seller shows up at closing and said they just found out that tenant B had not paid their rent this month per the property manager. 

Or will payments include principal?
