In my mind, the two are not related.I can't charge rent on vacant landthe configuration of a unit {studio, 1/1, 2/1, 3/2,...} as a market and FMRAssuming you're interested in developing raw land, there's lots of considerations before picking a specific configuration.

@David Hunter One of the more useful items I've seen before is a multi-device charger similar to this one:It has great shelf life with a branded logo, but I'd like to think of something as relevant to real estate as possible while still being useful.

Post eviction notice on the front door and back door, take pictures (Pay or evict), demanding full payment including late fees and other back chargers.

Like Alex I purchased well and charge rents that result in a reasonable ROI  which means I look for 8-10%.  

Normally, your policy would pay you because you could not charge rent during a time the property was not rentable due to a covered loss such as a fire.

I asked the realtor how much they charge renting out houses to refinery contractors. 

Most managers that I've met have a consistent charge rate (such as 10% of the monthly rent or a flat fee) which would help with any immediate answers on calls. 

@Paul SandhuYou running battery chargers off the inverter or actually running extension cords from the truck?

Interest chargers will not impact capital gain.

By my math you're both wrong I did 27/ 31 and multiplied by the rent and got $2,612.90 you charge rent by the month not by the day and prorate as a percentage of the month.
