I was quoting pool prices for my clients several years ago at approximately $40K (basic package 12'X24' including screen enclosure and paver deck) and then they doubled and more after COVID.

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.

They have help pages and support.Airbnb has a multitude of problems, including their extenuating circumstances auto refund to guest.Booking.com help I find very useful.

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)?

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.

Quote from @Jerem Kaawaloa: I have spent the past 20 years working in health care and have only ever purchased properties for my own use, including a home and office.

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.

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). 

There's also disclosures in there that have to be included in your lease paperwork.
