What should I anticipate in terms of cost for a 15 unit C class property?

I anticipate refinancing with our bank after 6 months.

The bid I'm getting to dry in the space is far more expensive than I anticipated.

I anticipate moving expenses to be in the ballpark of $2500 plus the cost of whatever we do in the interim (45-60 days).  

Also, I have found it to be very beneficial to get a home inspection after rehab and before listing so you know what to anticipate from a buyer's home inspection after you receive an offer. 

If the landlord is renovating in anticipation of a sale, he is looking for top dollar.

And with anticipated child support added in, just counting my W-2 income alone raises my DTI too high to qualify with all my debts total.So does anyone know of any lenders who would count that spare bedroom income in my DTI for refinancing?

I will likely just adjust the offer to cover the $ amount the seller would receive in rent.There are two factors that concern me in the potential difficulty in getting the tenants to vacate the property, 1 is they are paying very cheap rent for the stats of the home and 2 the grow room obviously was constructed with considerable effort which I anticipate may influence them to dig their heels in and potentially squat illegally. 

Always position yourself one-step ahead of the tenant and anticipate their moves and counter-moves.

While it's nice to purchase with the anticipation of year-over-year increases in equity growth, a 10% target is an interesting component of your projections.
