Hello I am new in the Real estate Wholesale market.and I have some new Leads but I need to find out after we agree to the purchasing prices with the seller and sign the contracts, what is the next step?

I've had a few leads recently that would make good rentals there. 

The MLS usually has lame deals,  marketing campaigns take a while to bare fruit, chasing leads is well chasing leads.  

All seem well thought out and fit the audience.

There's nothing wrong with being creative...it will lead to your best returns but, when it comes to federal loan programs...it's strictly by the book.  

Depends on your audience.

There are paid services for that kind of information and it blows my mind that some investors are too cheap to buy a $10 in depth search when it could lead to a much greater reward later.

After the long DD period leading up to the purchase I would say updating units between tenants.  

At the same time they are de-incentivized on educating the (now paying) audience they built on the drawbacks and dangers of following their program.

I would put less weight on school district for 1 BR and 2BR - your target audience will not be a family with kids in school age, maybe a baby.Approach it from the other side: how much is your target audience bringing home net every month?
