@Luke Salisbury, hi and welcome to BP.I think this is a delicate subject. 

They need to be the same size (or within 10% of the subject house), within about a mile (no more), and sold within the last 90 days.

Any guidance on what repair costs will be or what a property will resell for are subjective estimates and cannot be objectively accurate.

if that's the case, having an extra 20% in the deal from either buying low or adding value will be a big help in weathering the storm. this will make it that even if you ahve to sell, you could still earn some money or break even. additionally, with a multi it's generally more of a cash flow play, and if that's the case an economic dip won't be too big of a deal if you are cash flowing an acceptable amount with a buffer included. lastly if you get into a deal and have extra equity, you could bring in another investor in the future and "sell" the extra equity to them, while still staying in the deal. there are other options, like subject too's and rent to owns that may work here but for me buy low is the best defense. 

I know about Texas because I had a business there and I was subject to heavy taxes.

I figured the Subject line would catch  your attention lol so lets get to it 26 Year old , Passive investor with a few retail commercial buildings ( $700K average price tag )  all rented out  and a couple business i run , all owned by me . 

The replacement tax is not a huge deal; however, in MI you won't be subject to it.

Do you operate a STR or have knowledge of the subject?

If you are going to value the subject as though stabilized, you should assume that the vacant units are rented based on an estimate of market rent to estimate your PGI and reimbursement income.
