@Brandon SturgillDealCheck has a complete built-in glossary with explanation of every term/metric, including the exact calculation formulas used.

Another reason people are selling are guests and platforms (Airbnb) are becoming more demanding by expecting more from owners including refunds over the simplest things.

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

That includes going to the bank and getting a cashiers check.Pay them at the bank, get deed notarized there, then take it to Register of Deeds and file deed.I have done this a half dozen times to keep from missing out on a great deal.For what I'm paying any risk is negligible.  

@Mark Ross  don't include heat in rent on an ongoing basis. 

From google: “The Fair Housing Act (FHA) does not apply to certain types of rentals, including: Owner-occupied buildings: If the building has four or fewer units and is owned by the person who lives there Single-family homes: If the owner rents or sells the home without using a real estate agent, and they own no more than three homes Religious organizations: If the property is only available to members of the organization's religion Private clubs: If the property is only available to members of the club Senior housing: If the property is designated for people who are at least 55 years old Even if a property is exempt from the FHA, it must still comply with the law's ban on discriminatory statements, notices, or advertising.

Luckily, I did not include this unit in my underwriting when purchasing, so the survival of this property is not contingent on this situation.Continuing to optimize for management of the building when I move out, like moving everyone to online rent payments or adding remote accessible security cameras.Exploring opportunities to expand my portfolio—I've begun my hunt for my next 3 to 4-unit building to house hack, ideally in Lake View, North Center, or Ravenswood.This year taught me that real estate investing isn’t easy, but it’s undoubtedly worth it.

Information including but not limited to: - Median Sale prices for different property types (SFR, MFR, Condo/HOA, etc.)- Average days on market- Absorption rate- Historical data on rents and sale prices in the area- Population growth- Main economic drivers (industries, individual companies, etc.)- Crime stats... if you know specific zip codes/submarkets that you'd like to target, the best data will come from local precincts. - and more..I'd recommend remaining active not only here on BiggerPockets, but in other valuable RE investment networks that you can find - i.e. local meetups (meetup.com, eventbrite, BP local events). 

Does anyone know if there is any flexibility here, including if I can keep the HELOC if I have had it for 12 months (so stayed in the Primary Residence for a year after the HELOC started)?

As used in this Section 18, "Interest in the Property" means any legal or beneficial interest in the Property, including, but not limited to, those beneficial intereststransferred in a bond for deed, contract for deed, installment sales contract or escrow agreement, the intent of which is the transfer of title by Borrower at a future date to purchaser.If all or any part of the Property or any Interest in the Property is sold or transferred
