My question is what is the best way to do this, refinance first under my name then transfer to the LLC or visa-versa?

Usually someone who has purchased with Roofstock can refer you and then you can create an account and purchase which will make you eligible for the $1000 visa gift card.

Me and my fianceé are newbies from the greater Boston area and we are interested in small multi-family properties (tris and quads).

My Fiancee and I currently live in Portland, OR but are relocating to Metro Detroit after the wedding in September!

Do I need a special visa (B1 working visa)?

Your fiancée would benefit from looking at getting a w2 job because off the books income is not going to count.

In your neighborhood, you don't want to have a vacancy very long, because things can tend to 'go missing'.If one tenant has sufficient income to qualify based on your standards, but the (probably) student with no social (BTW, get a copy of their visa for your records, and proof they are a full-time student) does NOT have provable income or background, the ONLY way to go is to get first, last and security.Since you are living there, you will have a better handle on the day-to-day, and you MUST stay on top of things. 

I’ve written her an extensive text message and had a visa gift card i Usually give tenants.

The other problem is there is a garage / shed in the backyard the renter lets her fiancée store his tools in, and I am going to live in the other unit so I want the garage myself, and could see them pushing back on this.

Deste modo, as alterações dão uma proteção extra aos inquilinos com mais de 65 anos ou deficiência igual ou superior a 60% que tenham celebrado contratos antes de 1990.Esta proteção aplica-se nos casos em que houve falta de informação ou de resposta às cartas de atualização das rendas, quando entrou em vigor o Novo Regulamento do Arrendamento Urbano (NRAU), e que viram o seu contrato a passar para cinco anos, correndo agora o risco de serem despejados.Se os inquilinos viverem há mais de 15 anos na casa – o que poderá ser comprovado por atestado da junta de freguesia – o contrato só pode chegar ao fim se a casa for demolida ou sofrer uma obra profunda que obrigue à saída de quem lá vive.Há ainda outra medida que visa proteger os idosos e deficientes, nomeadamente aqueles que assinaram o contrato de arrendamento entre 1990 e 1999.
