Getting a Zero-money down deal is very rare, even with SubjectTo or seller financing, so I wouldn't count on it. You could probably do 1-2 deals with $10K depending on the situation/market you find. Just be sure to keep money in reserves as I've seen many people look to low money down strategies but get in trouble once they actually acquire the property because the cashflow isn't as great as they orignially thought after capex/maintenance.
