@Jaekwan LeeA house hacking inspection checks for structural integrity, roof condition, plumbing, electrical issues, HVAC systems, windows, insulation, base and attic damage, unit conditions, and code compliance.

For example, I know many people who have bought a house in Ewing for $200k and it's renting for $4000+ a month and this person has put maybe $50k into it over a couple years including a new roof, updated cosmetics, and was able to BRRR out all the money.

I've often seen ~2,500SF per unit, but looking to see what is out there.Also, the land is not entirely flat, and I'm new to development, so I'm trying to get some ideas on what might be good options for developing with this topography. 

You may have a flat $xx dollar amount added to the rent monthly (specified in your lease) for utility bill back. 

I guarantee it will deflate again, as it always has in past, or at least go flat for 10-20 years until incomes catch up.

Before or after accepting:- Lower the sales price  or lower the sales price AND lower seller credit (only do this if you are confident in the sale)- find a value add opportunity (I've had situation where we put new roof on and split the cost 50/50 with the buyer via credits to up the home's value to meet appraised value).

However, we faced a few unexpected challenges:A hailstorm damaged the roof while the property was under contract.The main water line to the property failed.

Plus all the necessary stuff, like plumbing and electrical, roof and gutters, all the things that a 100 yr old house is likely to need, unless recently handled.  

We had already done exterior repairs to the house including a roof, and an AC.  

renovation including a roof replacement Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
