I want to know if I buy a four plex under an FHA, claiming that one of the units will be my primary residence, can I move somebody into the unit I claim as my residence and collect rent from them without issue? 

For conventional loan amounts on primary purchases with 5-10% down and even FHA eligibility, but I'd imagine the properties that qualify are more specific?

Hello, My wife and I are in the process of turning our primary home into a rental.

@Kenton Guidry   Hi Kenton,  I have had replacement windows installed at my primary residence as well as at one of my rentals. 

Rates are hight right now and if your primary residents has a great rate the HELOC normally is the smarter play as long as your have repayment plan that allows you to risen and repeat.  

I understand that the Section 121 Exclusion for Primary Residence allows you to sell your Primary residence and not have to pay ANY capital gains taxes on the gains/proceeds - as long as you use those funds to purchase your next Primary residence.What I cannot seem to find the answer to is - what is the maximum timeline allowed from Sale of the first Primary to Purchase of the replacement Primary residence? 

Lender (One Brokerage from here on BiggerPockets) says we can't buy it as a primary residence if it's leased.These leased properties would be perfect because July 2025 is when they would move in.We DO NOT have 15-20% down for a commercial loan. 

For us it varies by market but in our primary market 15% plus a small monthly fee to help cover software costs etc if it's a lower gross property.That's full service, host doesn't have to worry about anything and can forget the property even exists if they want to.We do have tiered services where it's 10% (w/ no or lower monthly fee) if the owner wants us to only do one side of it (either manage bookings but not guests/cleanings/maintenance, or vice versa).25-30% used to be more normal but that's legacy pricing now, for a couple of reasons.1) Of course margins are much thinner for owners now that revenue has generally come down across the board from the peak, while home prices and interest rates have risen alongside that.2) Probably even more important, a simple supply/demand equation, particular to the case of increased supply. 

Purchase price: $137,999 Cash invested: $15,000 Sale price: $260,000 Rental House purchased in 2006 and was my primary residence until 2019.

I can't see a reason in the world to sell it to an LLC now since you want to maintain your husband and wife tax exemption on the future capital gain as a primary residence, but since it's rented now you may want to consult on that.
