I am one of the co-founder of Host that you mentioned. 

Ensure 90% of tenants meet preferred criteria.Target Audience:Ideal tenants are clean, responsible, and sociable single professionals, students (with co-signers), and military personnel.

But we dont discourage co op or try to steal clients from other agents..

I am not aware of any PM co that charges the same fee for the original placement.

Pay close attention to the capital stack, how much debt there is, how much preferred equity there is, how much the GP is co-investing, how much they project rents to rise organically every year, what exit cap rate they're assuming, how much cash reserves the property/investment will have, how much does the deal returns change when you add 50-200 bps to the cap rate, what is your breakeven occupancy and exit cap rate, and a bunch more. 

Purchase price: $560,000 Cash invested: $56,000 Co-sign investment.

.- thanks ...try reaching out to the local small to mid size  credit unions and banks in NJ ...contact the bank you  have your checking / savings with ...contact the lender that services your 1st mortgage for options .....regarding deprication - are you asking about the depriciation on the  primary home ( subject property ) being added in or  for the depriation from another property ?

Something like co-hosting STRs, real estate photography or video (including drone), something in the trades if you have those skills, part time agent, etc.

I am new to AirBnb co-hosting & currently oversee two properties listed on airbnb.

I need a co-signer and I want to use an fha loan.
