Gotta get creative and search for some seller finance potentials in order to get a good BRRRR deal. 

I think multi-fam has a great long term potential and am looking to get into that as well to diversify a bit more and have a solid base.

Once you have a solid foundation and feel comfortable both running numbers and assessing a property, talk with a lender and see what you will be able to afford.

By setting clear guidelines and fostering a culture of respect among tenants, many potential headaches with neighbors can be mitigated.

This deposit serves as a form of protection for any potential damages or outstanding rent at the end of the lease term.Most of the property management companies offer various convenient payment methods to ensure a hassle-free experience for tenants.

I'd seek to have them re-sign the lease and let them know you will be marketing the place as available to rent if they don't... and if they don't then I'd do just that, I'd start marketing the house as available (at the date the current tenants lease ends) to get some early interest from potential renters.

Late rent and potential evictions come with the territory of being a landlord.

$XX,XXX upfront and then $xxx per month or per year... whatever, the options are endless here on the agreement side and the additional benefit is there is NOTHING for you to upkeep because again the Tenant owns the structure, lastly if there is a default and your agreement allows it you may assess penalties to ensure it does not bring down your existing property's value, and beyond penalties if the default continues you can foreclose on the structure... the structure is your security. 

After I own it, I have a lot more tools, but these are my musts for looking over a potential flip.

My understanding on this is that if you build it unpermitted, the benefit at that time is that your property value likely won't increase because the square footage is not assessed to increase the value of your home and therefore the property taxes.
