This would typically involve taking a cash-out refinance or a home equity line of credit (HELOC) on your current rental to access the funds needed for the down payment on the new property.Regarding the lender fees, having two mortgages, one for the cash-out refinance and another for the new property, could result in additional fees, but it’s not necessarily double the cost.

Additionally, connecting with local real estate agents, property managers, and contractors in your target areas can provide further support/insights.What markets are you looking into? 

In short, we shouldn't expect much increase in ARV but an additional 1/2 btr can go a long way in increasing demand, appeal, and attracting better tenants while lowering turnover.If our budget allows it, we'll add it to the property 💪

If I were to purchase a SFR from a consumer I would INSIST that they employ an attorney.
