The sale price of a property is affected by a number of levers including supply and demand, replacement cost, interest rates, the riskiness of an investment, and, most importantly, the amount a buyer is willing to pay to acquire it.

I currently have one property that I own and live in with my wife that I used an FHA loan to acquire.

Purchase price: $621,000 Cash invested: $100,000 We have acquired 17 homes over the past year paying for them in cash.

@Alonso Fernandez MaldonadoYou would be acquiring a new loan based on the new value of the property.

I just acquired a third one which we purchased for cash approx 4 months ago  due to some fortunate inheritance. 

I currently own a few SFR's that provide me cashflow but have a goal for 2020 to acquire a multifamily or ideally an apartment building with a few investors.

You finance guy can easily let you know this before you acquire the property.

What kind of lender would I use to acquire the set of mobile Homes but doesn’t have any land to attach a lien to?

@Nicholas Hoffman personally if it were me and I could have a Do over I would continue renting and focus on acquiring assets.

With that said, acquiring a park with park owned homes is not a complete deal killer as long as you have a smart strategy to convert the homes to tenant owned and the experience to renovate and sell them.
