This is something I try to live by and teach my kids if I can - "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.

In order to do this you need to have deal flow and you need to know 1) How to recognize a good, profitable deal, 2) How to put together funds quickly to buy the deal before someone else does and in such a way where you are protected and the deal is protected, 3) How to run the project so that you follow the budget and don't overspend or overbuild, 4) How to attract an end buyer or a renter and which documents to use to protect yourself and the buyer, 5) If you are going to keep the property then you need to know how to set up the property from the start to best help you in the refinance later, and 6) You need to know how you are planning on managing the property from the beginning in order to make sure it will be profitable at the end.

While your condo snowball strategy builds equity, modest cash flow and HOA fees may limit returns.

You set your own payment terms with YOUR client and then find funding for them.The Capital Syndicate is a private lender firm that offers financing through their own company, but they also provide you with a list of about 150 other private lenders. 

This is after covering all expenses and setting aside a certain amount for reserves to cover future expenses like capex or vacancy. 

Bit more paperwork, but you get paid twice.Flat Fee + Profit Split (Repair Funding): You cover the repairs, but you set a minimum fee (like $15K) to protect yourself.

I'd be looking at multiple structures. we try to build below the average new build cost in our market in Columbus Ohio which is 515,000 last year and we target land 40-50k and urban core adjacent where we get higher price per square foot. we build for clients with margin around $190 a sq ft depending on multi or single. we can get that down in our triplex it's a little higher on our single family homes because of garages and limited economies of scale. hope that helps. idk Philly but if you show me the area and styles of homes I can give you some more insights. 

Difficult to defend places -- hillsides with limited transportation options, etc. -- won't be allowed to rebuild at all.
