I agree as well with the value being based off of current market rental rates, regardless of what the current lease rents are at or if a unit is vacant. You are purchasing assuming market rents (set by the condition, amenities, location, etc. of the property) so agree that a seller would likely question a request for a lower price or their receiving less at closing. I do get you having some concern maybe going into winter in WI and wondering if tenant activity will be there to fill a vacancy (with lots of leases and moving around happening spring-summer). Not sure when closing is, but you could ask the seller for permission to advertise the units now and hopefully allow for rental showings to try to get new tenants lined up with leases to be signed with you right after closing. If the units do need work, getting that done over the winter will also put you in good shape for spring, but do get your concern if you were hoping for that rental income in your first few months of ownership. If your Offer lets you "review and approve" of leases, and you feel they are not as expected and decide you can't live with the turnover right after purchase, than can discuss backing out with your agent. However, as mentioned already, there are positives to consider and as a rental property owner, turn over and vacancy is a part of the investment, so just getting some experience with that sooner in the process than you had planned on before review of the leases. If tenants are moving out right after closing, do double check the leases clearly show the security deposit they paid the seller and you collect that amount at closing from the seller (credit to you) so you have those funds to then return to the tenants when they vacant under your ownership.
