Off market deals are more like catching fish with your hands, and if you get your hands on one, it still requires a lot of work to uncover all the relevant information about the property and nurture the relationship with the owner - and after a few weeks you may find out the price is too high or they have chnaged their mind and are not selling after all.

The best wholesalers are spending more than 5k per month, and do that consistently for years until they can nurture the leads. 

My suggestions as you continue to seek lenders to refinance, it is best to continue to do your homework collecting information, getting to know your local banks, lenders etc and networking with them to build and nurture relationships to get a better idea and more prepared for refinance when it come after renting out your next purchase right property.

The biggest investments may take a few years to nurture! 

Nurture those seeds/relationships until they can bare fruit.

While hovering/napping I am nurturing relationships with potential sellers of specific properties I like and paying down/off my higher rate and higher risk loans. 

When you do eventually find it, hold on and nurture that relationship as if your life depended on it........your business life does. 

Relationships are also fostered and nurtured through timely and constant communication.

Do you need to figure out how to nurture zillow leads?

I've got a three properties actively listed and two rehabs ongoing for clients to sell when complete as well as one in escrow for a buyer, other buyers searching, and a few listings I'm nurturing for short term future sale when ready.
