You maybe already figured out an approach that works for you... but you could check out this Rookie Reply podcast episode that addresses this question.  

It's a great way to have a hands off approach.

My question here is how would you guys approach raising the rents on these tenants by such a large margin? 

Newer replacement windows, new exterior doors (originally the building used hollow core interior doors with a screen door as the exterior).I approached the owner of next door sometime in 2019 to see if they would be interested in selling. 

The quickest way to get started and see positive returns would be through Passive investing.

Any suggestions are welcome but looking for direct lenders, as we've already been approached by some loan brokers. 

How do you approach someone who's living in a $1M house and driving his-and-hers $$$ cars and explain to him that the fact that his wife is endlessly determined to prove to her own mother that she could have more kids and turn them out better on Sunday by documenting it on Instagram is the main thing holding him back?

Do you recommend I stick to my cash purchase strategy or approach a hard money lender?

This really clarified on how to approach lease options! 

I think a strong argument can be made for both approaches.
