There are usually some good, local investors that monitor those forums.

also I have a million questions like how much loan can you get approved for a rental/ is it same as your regular mortgage/ good agent/ duplex vs sfh vs condo etc. 

That means the higher your bracket, the greater the savings.I hope to make to make this one of my first regular tax tips here on BP. 

I intend to start regularly visiting the city I want to invest in after corona goes away.

Staffing to handle all calls, showings, maintenance, interior home visits on a regular basis and strong attention to detail when approving applicants.   

Actually I wouldn't use a person for that listing, I'd use some agency because it's that regularized audience and having a known brand for tenants as "the" place to look that drives so much traffic. 

Usually some good locals monitor that forum. 

Don’t count on tenants to replace filters regularly.

Other than that, you'll have to check regular maintenance items (i.e. roof, heating and air conditioning, plumbing, flooring, etc).

If tenants were unable to pay I would be able to cover my payments on my houses with my regular job, I take home about 1k a week.
