@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

I have been filling my pipeline for the past 4 months but everything thus far has fell apart.

Property has three commercial fronts and 3 apartments.

This home is not a luxury home so the insurance route seems overkill.2) Buy a worry free waiver and add it to the booking rate?

DM me your email and I can connect you with the organizer.The group discusses buy & hold real estate, both single family and apartments. 

Quote from @Shawn Questa: A few times I've reached out to Cash Buyers and they would tell me that they are a part of an Investment Group and that they are ready to quickly Close Deals would be happy to work with me.Later I would come to find out that they are actually a Group of Wholesalers, like me.I guess I would prefer to Work directly with the Investor, Cash Buyer or Flipper. 

Jeffrey:I'm connected to a large group in Indy that focuses on buy & hold SF and apartment (commercial) residential real estate. 

The idea is to convert a multi-family building into condos; but not in the traditional sense where you separate pre-existing apartments into their own condos; but in a way where you combine the common areas of all of the apartments in that whole building, and turn the individual rooms within those apartments into condos themselves; thus transforming the hallways, kitchens, bathrooms, living rooms, dining rooms, porches, balconies into common areas of the condos.

Too many low income apartment buildings near by / vacant buildings.
