Running numbers on 37 unit package deal

[Brian Pink]

I'm fairly new to investing. I've done several flips, and currently have one rental that should be ready to rent in a week, but that hardly qualifies for me as a proficient investor. 

I'm currently deciding on whether or not to purchase a 37 unit package deal. I'd like to show my spreadsheet and have more proficient investors tell me what you think. 

Off the top, I already know I'm not going to buy this deal for what the seller is offering to sell for, the cap rate isn't quite high enough for me. I was considering making an offer at 12% cap rate, which is what I'll upload for you to see. 

My plan is to fix each house up to have them qualify for Section 8 housing to justify a higher rent rate and net more per year. I don't have the numbers on how much it'll take per property currently, but I would be buying this deal based off of current rental rates and leases. I have all lease agreements (12 months) - I'm getting taxes. 

I based the mortgage off 20 yrs at 6% with no down payment if you all were wondering. 

I don't know if you'll be able to see this chart or not. If there's a better way to upload it, please let me know. Thank you in advance! I love being a part of a community that helps each other!
