about to negotiate a seller finance potential deal. Advice?

[Benjamin Cowles]

Going to meet up with seller to discuss potential deal with seller financing. something I've yet to do. I'm planning just to get a rough tentative idea of how we may come together the numbers for an initial proposal and take it to an RE attorney.

Despite all that I've learned so far in the last couple years I'm sure I'm going to forget to ask important questions and other important things to keep in mind. so if some things come to mind that beginners often overlook feel free to throw them at me.

This is 2200sf duplex in a B'ish neighborhood. maybe C+? My research suggests it's worth around $100/sf and rents at $.8-1/sf(not sure if you guys ever look at it that way but it came the easiest way to me).

I'll anticipate at this point it needs <$10k to get in top condition. Tenants in place paying $875 and $900.

I'm seeing I could pay up to $220k over 30 years at like 1% max APR to be good. Or at say $180k at 3%. Does that look too close?

I'm factoring in 30% of gross rent for PM, maintenance and vacancies adding a bit over $500 to the monthly PITI payment which couldn't exceed $1100 in order to net me $200/month from $1800 rent income. What am I missing?

Should I require the deed or if seller insists could a land contract be a good idea?

And lastly can anyone recommend a good affordable RE attorney in (Lee county ) Cape Coral/Fort Myers area? Thanks guys
