You can learn a lot from someone who's spent a lot of time on the property, and it doesn't cost you anything as long as you're polite and respectful.Lastly, you'll want to be ready for the tenants to ask YOU some questions as the buyer or agent. 

What initially drew me into DSCR was being able just to show the "W2", "income amount coming" and as long as the rent comps were in positively cash flowing everything was good, and not having to ping my credit. 

Consider factors such as location, property condition, future development plans in the area, and your long-term goals.Remember, patience and persistence are key.

As long as you do that, you will not get any pushback from a tenant signing a new lease with you.  

How long after I purchase the property do I have to move in?
