The house mentioned above I believe we ended up about $1500 in misc pipe repairs and adding a few sections of baseboard for the kitchen renovation and master bath addition.

It has been mentioned on here and Members were kind enough to give you a contact for Code Enforcement.I would be on the phone, pleading my case with the next breath.

I know you mentioned your in NY now.

I see @Adam Ward, you have mentioned meet ups.

Hey Kajal,For our LLC, we looked into building rentals and found mentions of construction company thru real estate meetups. 

You had mentioned you’ve attained seller financing, congratulations on that!

The vast majority of agents fail not just because they can't do the job, it is because most people who start a small business fail (they never have done it before).As @Robert Leonard mentioned, Gary Keller's book is a good read.

When you mention credit being ruined, I thought Hard money is when the house is used as the collateral and not your personal credit?

For example, hard money, although it has a high rate, you can usually close very quickly and if you have a good deal, you might not have to bring any money to the table.So, all things considered, private money is usually the best for reasons mentioned above, but that doesnt mean that other financing options should never be used or explored.

As @Stan Hill mentioned, always have them sign a lien waiver in exchange for a check.
