There are many reasons that I will provide but the biggest 2 in your case are that it will cost more than the value it adds and it is likely to make your existing SFH rent controlled.  

The biggest pitfall is when a landlord tries to be "nice" - non-paying tenants are literally stealing from you, treat them like the criminals that they are.To calculate reserves for vacancy costs We average about 2-3% vacancy across our portfolio, I use 5% as the number for reserves.

After screening what should I look out for my biggest issue is credit and late fees .

But what about the downsides?

The biggest challenge I have is that when you're creating a new posting of a vacancy, you have to wait for it to get approved.

That seems to be our biggest hurdle at the moment.

It would probably be a year or two before i could get my first investment property anyway. no downside, until i just learned it would be 4+ years for conventional loans.

I've checked the biggest employer is still a company like McKinsey, Deloitte or BCG.

Biggest red flag for me is her representation of credit docs, but nothing actually there on official report.

Let's see if you have "Bigger" numbers than mine.I think mine is the biggest...I meant the numbers lolYours truly 🙏
