If rents are under market, consider small increases or exploring additional ways to optimize your cash flow, such as taking on another roommate.Refinancing is also worth exploring in the future.

Additional Fees. 

I was able to get them in touch with an off booking sites place that had an opening in town.

So a community of these homes could definitely provide an affordable downsized housing option for active seniors (independent living style) - especially when you provide amenities on site, which will be required if you want to compete with other independent living style communities and apartment buildings.

Please let me know who you have worked with and why you like them (How many properties do they manage for you, how long have you worked with them, what you like about them etc.)When the unit is vacant, do they cover the cost for professional photography to rent it out again, or is that an additional fee? 

In my area an  U&O is only done when the house is built or an addition put on 

Also these deals are not one out of 100 they are the last 3 i have closed on to keep, you can verify on the county site.

Additionally, if the market conditions improve, you might have a better opportunity to refinance at a more favorable rate.5.

Quote from @Deandre Brown: When analyzing deals, a few additional factors I like to consider are whether the electric and gas utilities are charged per unit or as a single expense.

but I suspect homesites will drive the best values.. no one wants logged over sites for building ( generally speaking)  it works here in the Northwest because of the incredible shortage of buildable land. but in other areas not so much
