I have found that Redfin actually has pretty good search parameters to where you can look for listings that have been sitting a while that fit your buy box, and you can even do keyword searches for things like "as is", "investor", "seller financing", "guest house", etc. depending on what you are looking for.

I then rent for at least a year, if they pay in a timely manner and keep up the property I offer to seller finance the home to the tenant. 

There's a tenant that's month to month, rent is at least $800 below market rent, so I told the seller I need that unit to be vacant.

I have two properties (exact same property just across the street from each other) one is a seller finance that is coming to the end of its contract for balloon payment and the other is a fix and hold Interest only loan that is also coming to the end of its contract for balloon payment.

I started this a little over 3 years ago now.I think thorough research, and data will help make educated decisions, and the real winner in this market is finding a mix of at least 2 of the four:  Off market discount, fixer upper, lowball on market offer, or seller financed/subto.Also if you are planning to do it in a populated area I also think its good to take on the idea of not cash flowing for a few years, and also considering air bnb if you want to reduce costs even more.

I come across SFR in other states from time to time direct to seller. 

Purchase price: $15,000 Cash invested: $25,000 Sub to deal - paid the seller and wholesaler $15,000 + $7500 closing costs to assume $84,000 mortgage with a monthly PITI of $575.

I invested it into marketing direct to seller in the Milwaukee WI. 

95% of the time we get the seller to pay for the warranty.

Bought for $275k, seller finance, renovated $135k.
