Help with first deal

[Victor Vazquez]

Hello everyone, I sent out a couple yellow letters to people who own 4 plexes and got some responses. One guy said he would sell his four plex for 250000 that rents for 650 per unit. He said the interior is good and the outside and I told him I was interested and would like to check it out with a home inspector. He replied by saying that he wants me to put it under contract and wants $1,000 in earnest money. Could someone help me out and tell me what my next step should be? Thanks
