Sale price will be a little below market value with a Home Style loan (4% down), rehabbing ($80K-$100K) mom's home into a place my family and I can live in (better schools, bigger yard, and other benefits) comfortably with a growing family.We plan to renovate the attic of our current home and make some cosmetic repairs ($60,000 HELOC) that take it from a 3 berooom 1+ half bath to a 6 bedroom 1+half bath with a separate 1 bedroom apartment that has a livingroom and kitchen (apartment is already renovated).We then plan to rent the Air BnB for 2 years and re-finance for equity and leverage to buy more rentals.

The property is a rowhome, partially connected on both sides.The smell is strongest on the RIGHT side of the house towards the front inside the finished basement.This is the side that has access to the outgoing waste line.I was able to determine this by opening up several access panels in the finished basement walls on both sides and smelling the air in the cavity.A neighbor (two doors to LEFT) has developed the same smell in his finished basement at the same time.

@Eva Hambrick a few things...First, I obviously want a CPA who is a experienced in rental real estate; including things like depreciation, capital improvements vs maintenance expenses, passive activity losses, applying 1031 exchanges, etc.Second, as both a business owner and real estate investor, I want my CPA to understand that I have both earned income and passive income, and help me strategize how to reduce my tax liabilities from this standpoint.Finally, I want my CPA to be proactive in helping me plan and manage my tax strategy as part of my overall financial health all year long, not just file my tax return in April.
