Ultimately, it is up to you whether you would like to risk a void period by turning down an offer. While there is no "one size fits all" solution, we recommend owners consider a variety of factors and wisely weigh the benefits and risks.
Owners should consider market conditions first and foremost. Unless you are confident your property is competitive and will receive more (and better) offers, it may not be cost efficient to incur any loss of rent. Rather, it may be more strategic to send a counteroffer and negotiate with your renter.
As well, owners should carefully consider offers before risking a void period. Factors such as a reliable tenant or longer length of tenancy can provide many long-term advantages and offset a less than ideal offer.
