If you can find a local contractor willing to bend up material for you it is a DIY project.

Although I must admit that I have several years experience in being a licensed GC, and am also an architectural designer who always creates his own drawings and presents them for construction permit approval  at a cost to me of about $150.00 whereas it might cost you a few thousand dollars on top of contractor costs.

I enjoy both of those books as well, and my father was a big fan of Think and Grow Rich.

I would love to connect with reputable REI friendly Property Managers, Real Estate Brokers, Contractors etc., in Pennsylvania.  

On the other hand having a draw schedule and fund control with inspections before disbursements could be good if you're new to this as it could keep your contractors in line and it will force you to collect all the necessary paperwork in terms of Certificates of Insurance and W9's.

After all that is complete, then it makes sense to spend money on the inspections, surveys, contractor bids, etc.

If you do need to apply for permits, let your licensed contractors pull them. 

if you need to supplement the costs further you can consider renting rooms out in the unit that you live in but this typically is only an option for those who need the financial assistance (housemates are often not easy).You learn Property Management, if you like being a landlord, doing repairs and hiring contractors. 

And enjoy your last Christmas in your home with your family.

It's important that you find good contractors, good wholesalers, and good deals in order to make your returns as big as you want.
