However, since my target properties are lower end properties that often requires rehab before I can attract the best tenants at full market rent, I find myself doing a lot of work.  

I target other wholesalers and  estate sales.

I'd target houses in west philly, closer to upenn campus.

Typically, when doing an installment sale, does the seller (me) charge "interest" on the outstanding balance, or would I simply mark up the sales price to some fixed amount (which of course can be calculated using a target interest rate).thanks.

Also, can someone tell me how to target market?

1/2 way between blind and A&M is no man's land if you are targeting students.

The wholesaler doesn't want to give out information unless you demonstrate that you're legit.Technically sending out personal information and advertising a large bank account to someone through craigslist also make you a target of a scam, too so tread lightly.In order to get a proof of funds letter, your best bet is probably working with the bank that holds the money (or line of credit) you plan to use to invest.Also, consider a different approach in looking to meet the wholesaler for coffee in order to discuss more about their business and your criteria.

if you don't have mls you should download the Zillow app and research your target areas.

It takes time and perseverance/consistency.But isn't the whole point of targeted lists to find people that NEED to sell their house fast?

I target east end henrico some northside as well
