A Bank may have the lowest interest rate charged but does look at your worthiness the most to qualify.Owner financing may be the best way to go. 

Hello All,My tenantand I agreed on month to month, how much more should I charge for the month to month ?

It would have to be priced correctly to cover both parties (assuming my biggest take is the lot and a percentage for management and commission that my broker will charge.) 

., that's a bigger problem, but some people charge by the square foot.

There's no charge but I can't just go posting links.

I've met other investors and contractors in the area, so I know how much investors are paying and what contractors are charging. 

A toilet can be $ 100 and a handyman shouldn't charge more than $ 100 for install.

Consider how many people you are willing to have before charging for extra people.

So if you lived there for 3 years, they shouldn’t charge you.

You definitely don't want a situation where someone gets hurt by traps or poison that you place.If it is more related to the tenants being pigs than a hole on the outside then it may require some education on how to keep things clean and charging them for pest control if local law allows it etc.
