Hi my name is Han and I was an angel investor and long-time user of DIY Landlord online rental property management software called Avail, which was later acquired by Realtor.com.I have seen how Avail improved and introduced useful features overtime, to help Landlords find tenants quickly (example, one can advertize once on Avail and your AD will be posted to several other rental sites, free of charge), receive/process rental applications online, screen prospective tenants, easily draft state-compliant rental leases (and allow Landlords to clone previous leases when drafting a new lease), easily setup/manage rental payments (including auto rent payment reminders to tenants), and record/track property maintenance tickets and costs.If you are DIY Landlord like myself, you can try Avail using my referral link: https://lnkd.in/gfZGuVxz and get $50 in account credits when you sign up.

Philadelphia is really cracking down on Air BNB in April 2022.  

You will likely lose some money in the beginning, but that's how you start learning to screen for better team members and build a trustworthy team.

The downside of repair costs is in all the stuff you can't see online and all the stuff that novice investors miss on-site when they don't know what to look for - abandoned oil tanks, septic issues, foundation problems, asbestos, cracked sewer lines.

They don't screen tenants etc.

Me personally if I'm going to flip or keep a property and I want to remodel the bathroom the ease and cost-effective way to update a bathroom is Acrylic.Furthermore, Acrylic is extremely durable and can withstand scratches, scuffs, stains, cracks, dents and chipping.
