Even in the nice locations, most top out around $2,800.Of course there is also your increased insurance, vacancy, repairs, CapEx, and the never mentioned reduced rent on the main house since having a stranger living in your backyard usually isn't appealing to most renters. 

What worked for me was partnering with a trusted local business or coworking space in the area and using their address (with their consent, of course).

Your insurer could recommend one or you can check Google (and, of course, the reviews).

Folks forget rates did not drop below 6% until 2009, which was due the nearly collapse of the world economy and of course the rock bottom 4 and under was a result of the world shutting down due to covid.  

Likely your best course of action is to not renew their tenancy when the end of their rental agreement is reached. 11.

Typically hard money lenders will lend a maximum of 70% of the ARV so if you are below you will have more flexibility on the initial loan and the refinance (better terms or higher cash out) and of course more profit if you sell

And my experience was 18 months at best for term .. some went longer of course but many just went the first 12 months then moved and left a semi trashed house. 

Of course, everyone gets to set their expectations.

Hi @Cindy Truong yes of course please DM me and we can connect.

Of course the listed price may not be the actual rented price, but by tracking several listings for a while you can gain a better understanding of the market.
