I'd be happy to provide some recommendations and suggestions for your situation as a foreign citizen living in Miami.First, it's important to have a good understanding of the local real estate market, including pricing trends and neighborhood dynamics.

They can you you find good neighborhoods, purchase and rent properties.  

That’s 3 months of mortgage out of pocket and can make Chas flow negative. im also curious if people have experience doing section 8 in b neighborhoods or just c and d 

I don't use padsplit (weekly rentals); I rent on long-term leases in B Class neighborhoods.

Our logical process:1) Use Neighborhood rankings to narrow down area of city you want to invest in2) Focus on getting to know that Neighborhood(s), so you know the good & bad streets, block-by-block.3) Be patient to acquire properties on good streets that meet your buying criteria.Our rankings are done with a "bell curve" approach.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

Before investing here I suggest you read The Ultimate Guide to Grading Cleveland Neighborhoods to get yourself an understanding on the market.

Community engagement: Homeowners have a greater financial stake in their neighborhoods and are more likely to invest in their local communities.

We see it all the time with the conversations on what cars/vehicles folks drive :) here in BP there is a badge of honor to drive a 20 year old 250k mile car/truck :) Myself I saw my dad do some of this although he never got to the utra wealthy stage by a long shot but made good money in RE however it was not until he bought old style timeshare in Maui that he would finally take a vacation..
