I don’t think anybody can answer such a general question. I’ve rented to frum families and have had good results. I can give you some recommendations as a general rule and specifically regarding renting to frum as opposed to renting to others.
1. If this is in NYC apartment do not give a lease. The tenant can get away with not paying rent and it could take you up to a year to get them evicted. No lease means they’re renting month to month. This requires you give them one month notice for them to leave and much less of a headache if they stop paying rent.
2. You might feel much more comfortable asking a non-frum family for documenting income and a credit check.
3. If an maintenance issue develops on yom tov or shabbos, a frum family will be more understanding if there are delays in remediation.
