If you are looking to purchase a home that needs rehab I would sit down with a mortgage broker and discuss your options and tell them you want more info on the FHA 203k loan and the Fannie Mae Homestyle renovation loan.I have had several clients here in Connecticut use both loans with success and they typically chose one or the other based on their personal situation.

@Israel Torres Be sure to check out the features of each PM software.

Wholesaling as you may or may not know is a way of investing in real estate by placing properties under contract typically at below market value with the sole purpose of transferring that contract to a cash buyer at a higher price .

I don't know on that one but if it is normal 3 tab or typical composite shingles, I always put a layer on top unless it exceeds local code.

Run everything by them now as 1st consult is typically free.  

I wasn't aware of that feature.

But I don't do it for a typical rental because the co-signer tends to whine and cry when I try to hold them responsible.

Multi family is different typically than single family as it tends to sell on cash flow.   

New electric, plumbing, full house sound system, CAT5 and cable lines throughout, original light fixtures and features, new open concept kitchen, master bath, finished carriage house, sports bar in the basement, etc. 

If you want to sell the house, you should buy one that is in the middle of the group for the neighborhood, not the biggest and not the smallest and that has similar features to what people are looking for in the area.
