It's a fairly unregulated space (charging grandma $750 to puts around for 3 hours, after moving the old box from the horizontal sensor, which was the only problem with the garage door to begin with), so some combination of carefully reading reviews (you have to actually read them to make sure it's not 200 fake reviews), and maybe not giving them the full contract all at once, is in order. 

I also don’t have a problem spending the money to fight for this.

you can always call or email the tenant in regards to this matter. i personally smoke as well and just would want my tenants happy and not feeling accused as its a big problem with a lot of tenant v landlord situations around the country. you can always say you got a report of the odor of weed and was just verifying the smell with both tenants on the property. you can restate your conditions with smoking. you can always ask if they are legally able to do so as well (meaning medical card). depending on how you want to handle it, if you want to make it a legal warning to the tenant as well, you should write a written letter sent by mail stating you got a report of weed and this is a written warning in case this a problem down the road, you have evidence to show the court if it gets to that matter that this is not your first occurrence. best of luck!

Faced with the same problem I had to begin with, credit scores aren't great and don't have a qualifying cosigner for any type of traditional loan, mortgage or any type of equity refinance or HELOC, right now at this moment.

Try to arrange for an “open house” day for buyers to walk through with contractors and eliminate inspection problems/delays. 

I think this can be easily solved by sticking to a few banks and building a relationship to get the better rate/fees.

Problem with these is 1) they won't appreciate as quickly as those closer to the city and 2) it's a whole different tenant base, usually with a lot more management.

No problem @Jason B.

There is a very high demand for S8 properties so filling it with someone is not a problem.  

I am having problems finding DSCR lenders with favorable terms in Florida.
