First post ever, first offer ever

[Michael Jablon]

Good evening everyone, my name is Michael from south Florida. Within the last 24 hour I made an offer for a 948 sf. duplex 1/1 on both sides with a two car garage and a backyard with ample room for entertainment, my dog to run around etc. The specific area that this property is in is one block from the downtown area where it's up and coming (i.e vacant lots undergoing ground up construction for 'luxury' condominiums). I offered $20k below asking and $5k over my agent's suggestion. Tomorrow the offer expires. I am nervous someone will swoop in and offer a better deal (i.e cash, conventional) as my financing is via FHA. I can qualify conventional 10% down but I am sure what to do. Should I offer $10k more and keep the fha? Or Should I offer conventional and pay PMI? I also thought about offering both in two separate offers, fha at a lower price, conventional at higher. Previous owner passed away, son took possession and wants to get rid of the property. Any advice helps!
