We use 1/2 of apartment rent as a guideline in approximating lot rent levels. For example, if a two-bedroom apartment rents for $800 per month, then we would estimate that a good lot rent ceiling would be around $400 per month. Of course, this is not set in stone and, in fact, many REITs and others might charge $550+ per month under this scenario. But the point is that lot rents have to tie back to economic realities, and you can’t have a $400 lot rent when apartments rent for $300 per month. What all of these measures point out is that to have in-demand affordable housing, you have to be significantly cheaper than apartments and SFH. Some people think that you can have a successful mobile home park in a city in which SFH sell for $30,000 and apartments rent for $300 per month (read about my exploits in Louisiana for a real-life case study) – but the truth is that you can’t. That’s why you want to focus on expensive areas for housing, so that your park will have a ton of demand and you can charge a large lot rent.
