help with high end rentals in Nj

[Chai Sag]

Hi

I am renting out a house for $3300-3500 range

when I run applicants in NTN they tell me "accept with conditions" co signer , rent to income"

One of the applicants was renting a house for 2800 and paid well during last 2 years

this applicant makes 100k a year plus receive 650 month income

I know that in Manhattan some people pay almost 50% of income in rent

I am not looking form an A applicant, because he is going to buy a house and move out in 1 year

can I ask a sown payment rental ?

10 k and 12 times 2500?

or any ideas?

thank you
