Please I need advise on builders, cost, duration, financing and every detail possible!

@Michael Facchini - would you mind posting some details for general knowledge?

Have my eye on a 16 unit that has been hit with a death of owner and now illness of surviving spouse(at least that is what RE agent claims.) 

The laws vary greatly from state to state.Regardless of what area you choose, I can not stress enough the importance of seeing the property with your own eyes or if you are investing remotely, having boots on the ground that knows the area you are targeting. 

In the mean time I have to send the same contractor for the heater ugh..This tenant really opened my eyes, as many mistakes we have made, the only thing I was able to really verify was employment, she doesn’t have a “professional” job but she’s making decent $ and drives a 2017 bmw.

For lack of that being provided I request a detailed income and expense statement for each of the last two years that is signed by the seller or their CPA. 

@Bin Chen @Chris Rosenberg Some more details: Turns out the guy who contacted me is actually the seller's agent for the guy next door who is selling his house, and to sell mine would charge a 4% commission. 

Below I have included some of the details that I have, I am going this weekend to view the properties and find out more details:2 Different Duplexes:*$39,000 for Duplex #1 (Assessed at $47,500)*$20,000 for Duplex #2   (Assessed at $36,200)Duplex #1 Rents: *$600 and $400*$600 and $200All In $1,800/month.  

New member here - have found many useful tips & strategies on this site, but was never a member prior to today.I have a question about seller financing calculations regarding a deal that I'm currently working on.I'll spare you the full details of the deal, but I've essentially been able to get the seller to open up to a possible seller financing deal that would get me a great cash on cash return of near 20% on a good, solid property on the busiest street in town.Here's where I'm somewhat stuck (and I hope you can follow).
