I have campaign that way.

You've got your summers off since you're a student so you offer to help with a rehab deal, or do paper work, address and mail marketing campaigns, go door knocking for a Realtor to get leads. 

I see on investor websites and other types of marketing campaigns where they are guaranteeing an offer within 24 or 48 hours.

Im still learning and getting ready to start my first mailing campaign. 

@Leonard GilbertLeonard, To build and find motivated sellers, I would do a direct mail campaign by sending out about 2500 letters (500 per week) to seller's in a target area that you are interested in. 

How can I find out if my State has any Wholesaling restrictions?

When planning out a direct mail campaign, instead of spending all your money on 1 mailing, consider reducing the sample size, let's say for this example from 2000 letters to 1000 and mail the same list 3 or 4 times.So back to direct mail for apartment owners, finding the actual owner of large multi's can sometimes be challenging as most people, like myself included, buy the asset in an LLC for several reasons including legal protection.

Source and Seasoning the Down Payment: Conventional lenders (for the most part) will require that you verify, that, for AT LEAST 60 days, you have had: either the funds in your account OR you have earned (maybe a bonus at work, business profits, ect) or are entitled to funds (retirement savings account, inheritance, award prizes, proceeds from the sale of an assett, ect) and can prove where you obtained those funds from to show they are not a new debt or ineligible funds (funds that can't be sources or borrower funds).As to the LTV/CLTV: you will not be able to have the agreement between you and your fathers friend recorded against the property at time of closing, because of the CLTV restrictions, you can borrower 60% from conventional financing and get a 15% 2nd mortgage from your fathers friend, but, this would not normally make sense to do since the 1st mortgage is willing to go to 75% anyway.

I am looking to start a direct mail campaign in Philly. 

I bought a FNMA REO with a 90 day deed restriction.
